Tata Sky — Service subscription fee is being charged fraudulently every month

Address:	500029
Website:	www.tatasky.com

My tata sky id is [protected], i have taken this account in aug2015, each month, tatasky send a message asking me to pay the amount initially by 1st of next month, then following month they keep reminding of paymnet by 25th, like this the next month they reduced the subscription to 22nd of the following month, finally they pressurizing me to pay by 18th of the following month, so this is their strategy, every month they keep decreasing the time from 30 days to[protected] days so with in a month you are paying them twice. They have become cheats, when i called up their customer care, the staff informed me that they have revised all the prices and hence they resort to this tactic. When i got agitated and insisted on talking to the higher ups they kept me waiting and the so called higher up never came on line. Current;y we have suspended this subscription for this cheating attitude of tatasky, if anybody knows how to go about complaining to consumer court, please advise.
Thanking you, dr. S. R. Dasari.
