Tata Docomo — Frequent interruption in services

I m a user of tata photon + since last 3 years.my no is [protected].till recently the services were satisfactory.in the month of Feb15 it was not working for at-least 10-15 days.even after it started working again, its getting disturbed very frequently and the experience is very frustrating.its not expected from a brand TATA.the both the speeds are very slow.my 5 GB unlimited plan remained unused to a large extent in feb15. It is requested to take corrective action to improve the services and add up my remaining data usage in to current month balance. Not taking any corrective action to my satisfaction will force me to think of opting for other service provider.
