Paytm Fastag — delay in delivery and activation

Address:

Gautam Buddh Nagar, Uttar Pradesh, 201310

I am having horrible experience with paytm, after i ordered fastag. I ordered on nov 23 and they delivered wrong tag. I followed numerous times and every time there executive could not understand this issue and always closed the ticket. Always there line is busy and you have to wait 1-2 days of 20-30 times trials to get into the call with them. After so much of struggle i got my replacement but again following since a 10 days to get it activated. There sla was 2 days and that is also passed and still my fastag is not working.
