Urban Company — Refund not received

Address:

A 5/15 Happy Nook, ECTP IV

I had booked for toilet and fan cleaning on 15/10/23 morning and paid Rs 1425/- through my credit card. However, the booking had to be cancelled as no service associate was available that day. I got a message that the refund has been initiated.
Till date refund has not been credited to my card.
The help center of the App shows that refund was processed on 22/10/23. But mentioned that the reference number will be updated later. Till date neither reference number has been updated nor amount credited to my card account.
In the absence of the reference number I am unable to contact my card issuing Bank.
