I took Walky, wireless Phone, connection from my house at Gandhinagar, Hyderabad in Andhra Pradesh and I also took one mobile connection in the name of my 80 years old mother at Visakhapatnam with the intention that I can contact my mother free of cost since such a facility is promised by Tata Telecom. My land line number at Hyderabad is 64567943 and my mother's mobile number is 9291245112. Surprisingly I am unable to contact my mother's mobile from my land line. When ever I dial the mobile number of my mother voice message is giving the reason as invalid number. I gave number of complaints some of the complaint numbers given by tata telecom are 83920079, 84004937 & 84512609. Plese guide me in the matter
