Tata Sky — A/c number [protected] dysfunctional thought make advance payment for 2 months

I have made payment for my tatasky a/c but its not working. One month back a service engineer came when i faced same problem and deducted rs 200 as charges. Again in a month's time the same problem arose. I can't pay service charges every month like this. When calling customer care, they are very uncooperative. They dont want to help or trouble shoot and insists on service man to visit so that every time rs 200 can be deducted. This has to stop as this is cheating. Pls suggest what is the escalation process
