Dear sir/ madam
This is to inform you that i manish gupta has made a payment of rs 13965/- to my merchants acc ie simpl technologies on 4th of sept 2022 via google pay. The payment was successful and the ammount got deducted from my sbi bank account no [protected] ifsc code SBIN0061322 rohini sector 15 branch delhi.
But the payment was not credited to the merchants account nor it has been refunded back. Upi transaction id is[protected] and the bank reference id is[protected].
I talked to customer care of g pay they told me to approach bank for chargeback as we are only the payment platform. And when I reached bank they told it is the responsibility of the g pay. Now sir i m. The only sufferer which is impacting my records in my mervhants end.
I m suffering from the last 15 days and from. Nowhere I can find the appropriate result.
Kindly help me in this matter by refunding my money back to my account.
Thanks and regards
Manish gupta
