Tanishq — Golden Harvest Scheme - 1 month investment deducted but not registered or refunded

Address:

Tanishq, F8G4+R5V Near, Plot no 197 SSP Castle MIG Huda Complex, GNT Circle, HUDA Layout, Nalagandla, Hyderabad, Telangana 500019

I invested in Golden Harvest Scheme from Tanishq on September 30, 2022 for INR 5000 per month starting September 2022.

I paid the amount via GPay though QR code shared in the Tanishq Store situated at F8G4+R5V Near, Plot no 197 SSP Castle MIG Huda Complex, GNT Circle, HUDA Layout, Nalagandla, Hdyerabad, Telangana 500019):

Date: September 30, 2022

The store manager confirmed the amount did no go through and was refunded the same day for INR 5000.

Later, i received a message from Tanishq to make a payment on the link shared. I was not able to access the link. So i made the payment again on the original UPI shared at the store:

Date: October 2, 2022
UPI transaction ID:[protected]
Paid to: Tiitan Company Limited
titancompanylimited.[protected]@hdfcbank

I have confirmation from my ICICI bank stating the INR 5000 amount is deducted. The store manager also checked my bank statement confirming the amount is deducted however, Tanishq is neither registering me on the Golden Harvest Scheme nor is refunding me the amount i paid. The store manager mentioned they have not been able to track the amount. How is this a problem for the customer to solve?

The UPI Id is driven from the QR code on the store, the previous transaction on September 30 was tracked but not the one made on October 2, 2022? How is this a consumer issue? This is internal to Tanishq and as a consumer i want either to be registered to the Golden Harvest Scheme for INR 5000 per month starting September 2022 Or refund the money to me. Its been 16 days as of today and no clue where my money is.
Please help!
