Bigbasket.com — Deactivation of account and no refund of wallet balance

I have been a customer of BigBasket since 2018 and order regularly every week. Since yesterday, I was unable to log in using my credentials and upon contacting customer service, I was told that as per records, it had been noticed that I was misusing the Bigbasket policies, and hence, the account has been deactivated.

I fail to understand what policies I could have violated by placing an order regularly every week. Furthermore, I received no email or any intimation of any sort in respect of deactivation of my account.

Further, I am having a Wallet balance in my BigBasket account. No information has been given to me about this wallet balance and the money seems to have been usurped by your company.
