I am a customer of mts having data modem bearing connection no.[protected], all of a sudden i have recd msg from the mts stating that as you are a elite customer of mts family we have credited an additional benefit of 10gb data tom you.
On that day itself my connection is not working and while trying to open net it says that hence forth you can enjoy 4g network of rcom as mts network is now rcom network.
But while the rcom says that we are closing our business before 30th of nov 2017. While trying to mts nobody is answering correctly, local fellows not responding and no phone calls or toll free nos. Are working.
