Paytm — Shopper stop e-voucher not received. Query raised twice but no response

Address: 560001

Website: paytm.com

I ordered for a stopper stop e-voucher valued at 2000. it was mentioned as instant delivery by email. Once payment was made, status in paytm showed as delivered, however i have not received any vouchers/ emails from either paytm or shopperstop. I raised a query in paytm twice which acknowledge me with ticket numbers and stated to get back to me at the earliest. Its been a week, but no response. I tried to call customer care, to my disappointment, its only IVR. It does not have an option to connect with executive to speak. Kindly help me get the voucher or refund of money.
