Tata Sky — wrong charges dispute

Address:

Chennai, Tamil Nadu

the current month due amount differs with the last monht payment. last month i recharged for 490 rupees, this month due amount is 510 rupees. I just tried to contact the help desk and i was waited in the queue for more than half an hour. The last men about to clear my chat session is disconnected. This is highly testing the patience of a customer and this shows the poor customer service. I am really sick of your customer service help desk More over everytime when i try to contact the helpdesk number, it is always engaged and busy.how can we contact you if it is always busy. is there any other way to contact you over phone? can anyone please throw some light on my face.
