Complete run around

Since the 27th of February, we have trying to get refunded a 3 gigabyte data bundle reinstated as it was erroneously entered by the attendant for 30 days instead of a year. He refuses to accept responsibility and says he needs to find out how much data was used. We still received no information and every time we go to get information we are given the run around. We were promised some response over 20 days ago to no avail. We always told that we need to find out how much of data was used and each time we wait on the phone for hours to find out, we are told we cannot find out. Dhiraj was the attendant and the Manager is Ashna.
