CC Avenue — ccavenue has blocked my 'the mobile wallet' account

I have done the transaction of Rs10000/- on 05-Feb-2018 into my 'The mobile Wallet' app, using my Citibank credit card, transaction was failed but amount was debited from my credit card, when I have called 'The mobile wallet' customer support team has replied that they have not received money and I need to contact bank.
I have called the bank and asked the transaction status, they have replied that transaction was the success and if I want they will raise a dispute, then I asked them to raise a dispute. Amount reverted and settled on 12-Feb-2018. But on 20-Feb-2018, my mobile wallet has blocked my account. When I checked with them they replied that they have received mail from CCAvenue to block my account.

I have mailed a couple of times to CCAvenue they have not responded.

Attached the screenshot received from 'The Mobile Wallet' that they have received mail from CCAvenue to block my mobile wallet account.

what is the authority did CCAvenue has for asking to block my wallet account?

My mobile wallet account number is [protected].
