Tata Docomo — Unfair charges after cancellation of tata photon postpaid service and harassment to pay the charges

On Feb 1, 2015, I placed a called to Tata Docomo call center and asked for cancellation of my Tata Photo postpaid service. I received an email from Tata Docomo stating that cancellation service request has been registered. [Image attached]. I had paid all my outstanding dues on the day of placing the cancellation call.[Image attached] Then I received a call from a local Tata Photon center trying to convince me to continue with the service. I refused and I asked them to cancel the service. Then on March 17th, I received an email [Image attached], asking me to pay for the bill for Feb, though I had placed the cancellation request on Feb 1. After a lot of back and forth with the customer service, I could not resolve this situation and I was forced to pay the bill for Feb. I paid this bill on April 4, 2015 [Image attached]. Then on June 4th, 2015, I received an email [Image attached], asking me to pay for the bill for May. I was stunned and I called customer service and I was told that my service was still active and had not been cancelled and instead was placed in suspension. That was so ridiculous and I immediately asked them to cancel my service. I also told them that I would not pay the bill for May since I had placed my cancellation request in Feb, 2015. Nobody had any idea why my service was not cancelled in Feb, 2015. I kept getting emails asking me to pay the bill for May. I called customer service again and explained them the situation. I was told the outstanding dues will be dismissed by their customer representative. Now I started getting texts from tata photon threatening legal action and asking me to pay the charges for May, 2015.[Image attached]. This is unfair to bill me for the month of May, when I placed the cancellation request in Feb. Also it is unfair that when the customer service representatives had promised me that dues for May will be dismissed, I get harassing texts from tata docomo legal asking me to pay the dues. The whole thing has been badly handled by Tata Docomo with no proper communication between departments. It appears as though the company is scamming customers off their money without taking any responsibility which is why I cancelled their service in the first place.
