Tata Sky — Unable to talk to customer care or any helpline service

Dear all, during the time of cricket T20 world cup I had received a call from your office a lady's voice and my running pack change to 440 sports pack. Now Im very much unable to afford from my current income . therefore kindly change my current pack to Dhamal mix pack for 250 or 290 pack. I had tried many time to your customers care nos. as well as helpline nos. but its not working . Some time your marketing team call but they even don't gave me any time to change my pack instead they cut the call. Therefore due to not getting of communication to the customers care I have this opportunity to talk through mail.
