I switched into TATA network because there were lots of attractive offer, but from the second day I realized that there are only promotion they are doing but in ground they even dont have enough network to handle demands.
So after completely frustrated from the wonderful exp I decided to switch the network and raised a port request but most horrible thing is happened this time first time they have cancelled and I asked for the reasons and they said you not paid the outstanding and they have even not submitted the bill for me and in second time after rejecting the first request they cancelled despite I daily called them for status update.
NEVER EVER GO FOR THIS NETWORK SERVICE THEY ONLY KNOW HOW TO LOOT THE CUSTOMERS AND TOURCHER THEM
