Bigbasket.com — Bigbasket Account blocked

I ordered fruit juice and it is expired so I contacted the customer care and they arranged for a pickup but after sometime they blocked my account citing misuse.
How can they say that I m misusing the delivery person didn't even come to pick up the order and how can u confirm that I m misusing the account..ok for suppose i[censored] feel that i m misusing u should deny for pickup and refund but u directly blocked my account which has 5000 rs in my wallet balance and refusing to provide wallet balance..how fair is it.. please check and help me in this situation.
