Uco Bank — Refund initiated by Amazon but still not received

Sir
I have ordered two earphones on 12/02/2021. I cancelled the order as i get it in lower price but i i have not received my product.
Amazon initiated the refund on date 13/02/2021 and it was expected to come on 17/02/2021.
Amazon gave me the reference id[protected] but the UCO Bank has still not credited my money.
This is urgent please help me as soon as possible.
