Axis Bank — refund is not received in my account

My refund was to come from flipkart. Rs 12687 and rs 8, 091 flipkart says that we have sent the refund and the refund has been received on your account axis bank on november 6, 2018. Then i did not complain about flipkart, i did not get my money, then flipkart said that if you talk to your bank customer care we will send confirmaiton mail to you. Then i call aesyas bank's customer care very often and they do not give any answer. Then i sent the mail to axis bank and also sent the whole details. They have no answer and i am being ignored. I had been visiting flipkart on october 24, 2018 from the bank. One rs. 12687 and another rs. 8091.
