Tata Sky — inability to view channels and no action despite repeated complaints

we have two tata sky connections - [protected] and [protected]. for the last 45 days or more we are not getting any of the English language channels. complaints have been placed on helpline numbers and numbers being flashed on tata sky. we receive messages saying technician will visit at such and such time and date but no body turns up. of late the helpline number says if you have a channel viewing complaint we will get back to you as there is congestion but nobody gets back. never the less as consumers we are being charged for the services that have not been avaialbale and are not avaialable. this is a serious breach of cunsumer and service provider contract. Kindly take immediate action.
