Indian Bank — amount refund not yet credited to account

Address:

Samrat ashok nagar O.T section ulhasnagar-3 near balaji pancard office, 421003

As I have done a transaction from amazon and success but I canceled it so there was refund amount initiated from their end on same day 15/10/2019 at 08.57 pm and the refund reference no is: 1CW7MJL60000K19Z6DYY but amount has not been credited in my account till date and continuously I am contacting customer care for this but not getting a reply for this. As per them contact branch for complain, but its no use they only harass people do nothing to the matter. As per Amazon, they instructed to file a charge dispute. Please look into this matter as its very serious.
