Casino delaying paying out
Reason: Delayed payment
I have been left with no choice than to make a complaint about Cosmo. My account is stuck now and they are refusing to withdraw my money. I have attached emails from them clearly showing my account is fully verified and yet they still delay and delay paying me out without any time frame at all, it has now been nearly 5 weeks and they are showing no effort to resolve this. Something that would take a mere 5 minutes to sort. I have also shown attachment of my account showing my balance and username. From reading other complaints I know they will use this complaint as yet another opportunity to delay another 2 weeks but I would like this resolved as soon as possible so i can withdraw my money.

Coffee77 2 weeks ago Thanks @askgamblers. They have now stopped me even being able to place a bet. You have done all you can and i can't adhere to this breach of privacy so if you must close this case because of that then so be it. Thanks again for the help.

Cosmobet Casino - Player’s account has been closed and funds are delayed.
Cosmobet Casino - Player’s funds have been confiscated due to inactivity.
The player from the United Kingdom found her account balance of £1906 removed by Cosmobet due to alleged inactivity. She claimed she had not been properly informed about the potential confiscation of her entire balance and requested a breakdown of the deductions, the relevant Terms and Conditions, and evidence of prior notification regarding the policy. The complaint was reviewed, revealing that inactivity fees had been applied in accordance with the casino's Terms and Conditions, which the player had accepted, and that notifications had been sent via the account notification system and email. The casino required the player to complete a verification process before any further assessment or potential settlement could be considered. Due to the player's lack of response and cooperation with the verification request, the complaint was closed without resolution, though the player was informed she could reopen it in the future.

Cosmobet Casino - Player's withdrawal has been confiscated.
The player from the United Kingdom had deposited £180 and received a bonus that led to a balance of nearly £16,000. After attempting to withdraw £7,000, his withdrawal was rejected, and the funds were confiscated by the casino, despite having met the wagering requirements stated in the terms and conditions. The casino had applied a maximum withdrawal limit of £100 on winnings derived from free spins, as specified in their terms. The player was reportedly offered a partial payment of £300 by the casino. Due to the player's lack of response to further inquiries, the complaint was closed without a full resolution.
