Sir i have bought red chief mens leather rust boots from amazon.in on 18 august 2018 at 7:14 pm at a cost price of rs.1826. I have made an online payment of rs. 1745 by jkbank master card and rest of the payment of rs. 81 by amazon pay. Then i cancelled my order and received a refund of rs.81of amazon pay but not received the payment of rs. 1745. Whereas i contacted customer care of amazon.in they said me they have refunded the whole amount and it will appear on 29 of aug 2018 but the same was not received by me from j&k bank ltd.
Here is the referencence number: 202054 which amazon has sent to me.
Please resolve the matter soon.

Thanking you
