MakeMyTrip India — no resolution for assured voucher

Address:

Casagrand Pavillion, RH 193, Navalur,Thalambur road,, Kanchipuram, Tamil Nadu, 603103

My accommodation on 1st nov at pondicherry was cancelled by hotel person due to unavailability of room. However there was no communication from anyone on this and we were standing infront of hotel for 3hrs at night with two 3-year old babies.
After a long discussion, mmt person had confirmed that my amount will be fully refunded and along with that a travel voucher of 2000/- will be shared.

After 10-15 follow ups for the same since 2nd nov, i havent received any confirmation on the same.
Reason confirmed after multiple follow ups is that my email id is not registered with my mmt account.
I dont think so it is that difficult to share a voucher even if the email id is not registered.

Very bad experience.

Venkates
