Zomato — negligence, and banned without any grounds

Address:

560077

So some time back, just as usual i was ordering my dinner from zomato, after the food got delivered i found a piece of stone in the gravy, i reported the matter to zomato straight away and the provided me a refund but next morning when i woke up i got this message saying my account is blocked due to suspicious activity. First of all i provided them with relevant and satisfying evidence when they processed the refund then they ban be rendering my unable to use the discount provided to me in from of zomato credits. I tried reaching to them on email but got no resolution saying that its a system made ban and cannot be undone and did not provide me any basis for the same. Later contacted them for 1 last time mentioning of taking legal action if the issue is not resolved but that email has not been responded from my side even after asking for follow-ups. Kindly help me out on this one what am i supposed to do? They also say if you believe it has been done in error contact us but when you do that they say this is done by the system and we cannot undo it. Then why the hell did you even ask to send a mail when it cannot be undone?
