Paytm Mobile Solutions — not able to redeem promo code received

Address:

Ahmedabad, Gujarat, 380061

Hello support,

I had registered a number of complaints to get my issue resolved. But there is no response and support from the paytm.

See below issue.

I had purchased a parle marrie biscuit (Bakesmith) and got the unique promotion code inside that package (As they have promotion going on with parle company)

When i tried to use that unique promotion code paytm application as well as paytmmall application. I am not able to redeem that promotion code.

It is giving me a message that promotion code is not valid. I have double checked and found that promotion code is valid.

The same case is happening with other promotion code which i have received.

Please reply to the issue and how to resolve it.
