Amazon India — refund on purchase of steam iron

Had received a faulty iron which was returned on 14th august 2018 and acknowledged by amazon. Refund was initiated on 21st of august 2018 and 3 bank accounts where updated, but refund no received yet. My amazon.in order #[protected]. Has followed up with the customer care at amazon but in vain. The bank account was updated on 3 occasions as required by the amazon customer care representative. I have even changed my account name to my wife's name and furnished her account number but even after doing all these i haven't still received the refund and all i can here from the customer care representative is that my account details are wrong.
Please i request you to solve this issue for me
