sir, read ur article....its good to have some body mentioning it .i and my frnds hve faced same problems many times.so what we concluded was if you pick up the call frm your service provider regarding any schemes and tunes for ur mobile ...do not answer cuz smetimes by default they can set the offer r hello tune fr u.nw how to identify: mostly they call frm the same no so u can save those numbers maybe 3-4 with sme names n should not recieve it.nw for redeeming the balance u can talk to the manager or can tell them you will be proceeding 2wrds the consumers court.best of luck.hope saving nos n nt picking up the call certainly helps.
