Union Bank Of India — Amazon initiated the refund money with the Refund Reference Number but refund money not credited to my Union bank account

Address:

Union bank of India, 169 B New Sunita Apartment, Sion Main Road, Sion East, Mumbai-400022, District- Mumbai, State- Maharashta

I had purchased products through my union bank debit card on Amazon on 25th September 2021 having total Rupees 19, 801/- which I cancelled those products on 27th september 2021 before receiving the products. The Amazon initated my refund with credit date 02 october 2021 but It has been more than 2 weeks working days my refund amount i.e Rupees 19, 801/- not yet credited to my union bank account.

I did the complaint on Union bank customer care (Complaint No. [protected]) against Amazon but bank is taking much longer time in the process. I visited many times to my Union bank branch but they are not helping.

I am mentioning here the Refund Reference Number (RRN) provided by Amazon
