Avoid
Update: I have received the £9 remaining balance after this review, however my email reply is being ignored again since the 23rd of July. I self-excluded from Casumo after becoming concerned about the constant pop-ups and interruptions during gameplay, which I believe negatively affected my gambling experience. When I self-excluded, I still had around £9 left in my account that I was unable to withdraw.I submitted a formal complaint over three weeks ago and have sent multiple follow-up emails, but I have received no response whatsoever. The lack of communication and failure to deal with my complaint has been extremely disappointing.As I have been unable to get any response from Casumo, I will be escalating my complaint to their Alternative Dispute Resolution (ADR) provider and raising my concerns with the UK Gambling Commission regarding their handling of my complaint.I expected much better customer service from a licensed gambling operator. Ignoring customer complaints is unacceptable.
