Andhra Bank — refund amount to be credited-reg

I have ordered a product from a shopping website (Amazon) and returned that product and after returning that i received a message from amazon that my amount was refunded (I. E., on 27/1/2020) and usually every time i used to get my money in my account just after they refunded but this time refund money did not reflect in my account. Amazon had sent my money to my account but my money did not reflect in my account.in the message, it was mentioned that money would be reflected in 5-7 business days. So, on that note i waited for more 10 days but then too i did not get my money. I contacted andhra bank customer care and then visited my respective andhra bank branch (Nakkalagutta branch, warangal) in which my bank account was present but none of them resolved my issue. This is the second time i m complaining about this. It has been almost 6 months. Hoping that u would resolve my issue

Amount to be credited in my account:3529/-
Amount credited by amazon on:27th january 2020
Bank:andhra bank (Nakkalagutta, warangal, telangana)
