PhonePe — account blocked for irrelevant reasons

I am yash and i have phonepe account with phone no. [protected].
I received a message from phonepe that there is an offer that when you will make payment to a merchant than you will receive some scratch cards. I made payment according to the rules and received some coupons and cashback in wallet. Next day phonepe blocked the cashback wallet and today they have blocked my phonepe account.

When i contacted customer care they said that my account has been blocked due to security reasons and will not be reinstated. I wish to get it unblocked asap as i have no. Of transaction details in it which is needed to maintain accounts. Also, i made transactions according to policies as offer received by me. If the offer was fake then it is not my fault and why they have to block the account. It would be very kind to get it reinstated.
