WinTingo Casino - Errors followed by missing funds

I contacted support regarding an error message I keep getting during gameplay. I've deposited $40 into my account and have begun to play Multihand Blackjack with bets like $2, $4, $10 and even $15 and $16. After one round the second round gives me an error saying: Your request could not be processed because we did not get a response from the Account Management System. Please try again or contact the help desk quoting error code 211. On top of my problem whenever I lay down a bet, this error message seems to play out the bet I placed, giving me an automatic loss. I tried clearing it up with support and below is our conversation: You are being connected with our support team. Thank you for your patience.
'Iris' will be helping you with your query. We’d appreciate your feedback on our service in the survey after the chat.
Iris: Thank you for contacting support, how are you doing today?
John: Hi Iris, I told John earlier that I've been experiencing problems with games on Wintingo and he suggested that I restart my computer after deleting cookies and cache. Unfortunately the problem persists
John: I also have been playing Multihand Blackjack and have won a few rounds, to which my balance should be in the $70
Iris: what kind of problem is this John?
John: It is an error 211
John: I play one game/slot pull and the 2nd seems to give me this error
Iris: looking into the error codes and cannot pick up the 211 code
Iris: do the games load at all?
Iris:
John: sometimes they do and once I play them they give out that error message
John: The message says: Your request could not be processed because we did not get a response from the Account Management System. Please try again or contact the help desk quoting error code 211."
Iris: that is strange are you on the computer?
John: Yes
Iris: is your computer connection okay?
John: Yes, everything is fine on my end
Iris: I will be right with you.
Iris: it generally is a matter of clearing your browser history and restarting the device
Iris: you can send us a screen shot?
John: Sure, which email address do you want me to sent the screen?
Iris: floorm­ana­ger­@wi­nti­ngo.com please
John: Thank you for the information!
Iris: only a pleasure, thank you

In my humble opinion, live chat could be stalling or it could just be me. This discourtesy that I experienced must be settled right away. I would appreciate it if Wintingo returned my deposit, it's only fair since the errors gave me a sour experience at the casino.

Dear @Icymod,
Any updates regarding your complaint?
Thank you.

They've told me to wait for the relevant department to get back to me as they're still investigating.
