[Resolved]  Airtel — bill conflicts

I was told abut a plan with monthly rentals of Rs.250 in that i was given 1000(one thousand) mins free for A2A calls.so for this I was agreed to take a new connectin.after using this new number for few days i got to know i was cheated as the plan which was told to n the plan which was given to me is totaly diff n i was geting charged for even A2A calls.when i complained against this to customer service my plan was changed but now airtel insisting me to pay the bill for the period i used my connection for A2A calls.As i was told A2A 1000mins free i calld A2A more.now how cn i pay dis bill as i was told dat A2A is free.but for this issue my outgoing is barrd.though i hv discussd the same matter with many ppl calld frm their billin dept.
