I AM USING TATA PHOTON PLUS (PHOTON NO : 9230519397) FOR MORE THAN 5 YEARS.FOR LAST 7-8 MONTHS.I WAS NOT ABLE TO USE MY PHOTON DUE TO POOR CONNECTIVITY.I HAVE COMPLAINED MORE THAN 10 TIMES.BUT THEY ARE NOT ABLE TO SOLVE MY PROBLEM.THEN I HAVE DECIDED TO STOP THE PAYMENT FROM LAST TWO MONTHS.AFTER THAT THEY HAVE SENT A ENGINEER TO MY HOUSE AND HE RECOGNIZE THAT THERE IS A NETWORK PROBLEM.THEN I HAVE TOLD THEM TO DISCONNECT MY CONNECTION AND REFUND MY PAYMENT WHICH I HAVE PAID FOR LAST SIX MONTHS.BECAUSE THEY KNOW THAT THEY DON''''T HAVE ANY SERVICE IN OUR AREA.SO THIS IS REAL FRAUD.EVEN AFTER DISCONNECTION REQUEST, THEY ARE SENDING ME OUTSTANDING BILLS AND CONTINUOUS DISTURBING ME OVER TELEPHONE.THEY HAVE SEND ME A BILL AMOUNTING RS.1232.00 .THIS IS TOTALY FRAUD BILL BECAUSE I HAVE NOT USED MY PHOTON FOR LAST 8 MONTHS BECAUSE OF NO NETWORK IN OUR AREA AND THIS IS RECOGNIZED BY THERE NETWORK TEAM.TATA SHOULD REIMBURSED MY LAST SIX MONTHS PAYMENT WITH INTEREST.
