Quickr — refund amount

Address:

122001

My nam is abhishek, i was sell sone items on quicker last year. The amount accumulated in my qickr account is rs 8537. On 5th april 2019 i have received a message that we have initiated a transfer of rs 8537 in your bank account. You will receive payment in 4-7 days but after 5 months i haven't recieved a single penny.
Called quickr customer care many times but nobody responded. It's a very disgusting approach from quickr it's my hardened earn money please give it back.
