Slimking Complaints: How Disputes Get Resolved

Raising a dispute starts with a written email to our complaints address, not live chat. Our Complaints Resolution Committee then delivers an outcome within 10 days, extending only for complex cases.

How to Raise a Complaint with Slimking

Every dispute at online casino Slimking starts the same way: a message to our support team through our support channels, explaining the issue in plain terms. If that first exchange doesn't settle the matter, the next step is to put the complaint in writing and send it to our dedicated complaints email address instead of continuing through live chat. This two-step route exists so that straightforward questions get handled quickly through chat, while anything that needs a formal investigation is tracked properly in writing.

What your written complaint must include

A complaint only moves forward once it comes from the email address registered to your account. It should state your account username and your full registered name, so the file can be matched straight away. The subject line needs to contain the word COMPLAINT together with the reason for writing — a late withdrawal, a disputed bonus, or an issue flagged during verification, for instance. If you're not sure which address is registered to your account, our sign-in page can help confirm it before you write in.

The body of the email should give a detailed summary of what happened, including specific dates and times for every step of the dispute. Complaints missing these details take longer to process, since the Complaints Resolution Committee has to request the missing information before it can open a file. Vague descriptions slow things down, so it helps to note exactly which transaction, bonus or game round is in question rather than describing the problem in general terms.

What Happens After You Submit a Complaint

Once a written complaint reaches our complaints email address, it is passed to the Complaints Resolution Committee, the internal team that reviews disputes and decides the outcome. We aim to give a decision within 10 days of receiving a complete complaint, though cases that need extra checking — a disputed withdrawal, for example — can take longer than that. Complaints about a specific game round are checked against our server logs, since the result generated by the Random Number Generator on our game server prevails over whatever appeared on screen during play. That 10-day window starts once every required detail — the account username, the registered name and the specific dates involved — has actually reached the Committee, not from the date of the first support message.

If a complaint cannot be resolved to a player's satisfaction internally, we refer the matter to external dispute resolution rather than simply closing the file. This step exists for cases where our own review and the player's account of events still don't match after the Committee has issued its decision.

Any correspondence we send about a complaint is treated as received five business days after it is sent, which matters if a reply arrives late or goes to an old inbox — it's worth checking the email registered to the account referenced in the complaint before assuming a message has gone missing. This 5-business-day rule applies to every notice we send, not just complaint decisions, so it's the same window to keep in mind for any official reply from us.

Complaint and Dispute Timelines at a Glance

A dispute rarely runs on a single clock. Different stages of a complaint — from the first message to a final refund decision — each carry their own deadline, and missing one can mean starting the process again. Here is what applies once a complaint with Slimking moves past live chat. A support chat reply can come back the same day, but anything that escalates into a written complaint moves onto the schedule below instead.

StepTimeframe
Written complaint outcomeWithin 10 days (may be extended for complex cases)
Refund request windowWithin 24 hours of the transaction
Refund responseWithin 10 business days
Correspondence deemed received5 business days after sending
Finance department hours06:00-17:00 GMT, Monday to Friday

Refunds and written complaints follow the longest windows, while a basic support reply moves faster; checking the finance department's hours before calling also helps, since requests outside 06:00-17:00 GMT on weekdays wait until the next business day.
