Videocon Industries — displaying signal not available

My cust i'd is[protected] this is from morning onwards showing on the screen signal not available while there is no rain after that also tried to connect with the customer care also but they are also not giving any solution for that unless they are saying for an engineer to visit to our home and to pay him 200 which is unnecessary and i am sure after paying amount o[censored]r subscription and than seeing this signal not available i am not going to pay a 1 rupee to anybody so kindly check ur connection and give solution for this bcz i haven't paid to see this black & white screen, i am already very upset with ur low class service and thinking to throw this useless box check on this issue and give me a solution asap.
