Idea Cellular NCR - IDEA DE ACTIVATED MY NUMBER EVEN THOUGH THEY HAVE Rs.3000 DEPOSIT

MY ACCOUNT HAS A CREDIT BALANCE OF 3000 BUT IDEA STILL STOPPED BOTH INCOMING AND OUTGOING CALLS FOR MY NUMBER.... REASON:- THERE IS SOMEOTHER OLD NUMBER WHICH HAS A PENDING BALANCE OF 1000, AFETR A LOT OF CALLS FROM MY END AND OVER A 100 EMAILS I FINALLY GET IN TOUCH WITH SOME PERSON WHO ASSURES ME THAT MY NO WOULD GET ACTIVATED AND THE PENDING AMOUNT WOULD BE DEDUCTED FROM MY CURRENT ACCOUNT.. BUT FOR MORE THAN 3 DAYS NO ONE HAS CALLED BACK AND NO ONE IS EVEN ANSWERING MY CALLS.......... THIS COMPANY IS WORSE THAN A BLOODY TEA STALL OPERATOR ON THE BUS STAND..... HOW CAN THEY STILL HAVE A LOYAL BASE OF CUSTOMERS
