Paytm Mobile Solutions — code not working

Address:

Chandigarh, Chandigarh, 160014

I must say that paytm services r pathetic. They have no system that one can speak to them all fraud.
I purchased coke and in that i sent one mesg and got mesg back that i have won rs 50 paytm mall cash back code c3yuhxyxxtmkj.
What a fun this code does't work.
Its better stop using paytm as they have no courtesy to call back their customers. Big fraud... And cheater.
