I didn't get the promised cashback! Before assuming it's a mistake, should I check if the Jiomart-MobiKwik offer had hidden activation steps or terms? Honestly, with support this slow, can I even rely on MobiKwik for my future payments?

I'm looking into AU Small Finance Bank's 12-month FD (7.25%). If you've used their FDs, please tell me about your experience and the returns.
