Amazon India — regarding refund of rs 549 pending since 5th june 2020

Dear sir/madam,
This is to bring to your knowledge that i had done online shopping at amazon on 23rdmay2020 of rs1121.66. Purchased 2 books of rs 572.66+rs 549 out of which amazon cancelled the second book and initiated refund on 5thjune2020 but till date i haven't received the amount. Amazon has also not provided the refund reference number so that i can contact bank for help. My reference number for the transaction of rs1121.66 is[protected]. Regarding this i had complained to amazon twice but all in vein.
Please look into the issue and try to solve as soon as possible.

Thanks & regards,
Amardeep ghosh
