its been like 3 yrs i have been using t mobile n i have a family plan with my sister, we have been using hello977.com phone card to call Nepal and we never called Nepal directly, but my t mobile bill from this month shows that i have been directly dialing Nepal which i never did and the bill for this month is $1500, my monthly bill is around $100.
my bill shows first the local access no of calling card and some time at the same time and some time after a couple of min the no from Nepal i dialed (which i never dialed before dialing local access number).
date         time      destination       number          call type   minutes   charge

i called t mobile customer service this morning and describe what happened and tell them how is it possible to call 2 numbers at same time, but they told me it was my negligence i told them i m not that foolish to dial Nepal directly not once but several time, but they told me it was my fault and they cant waive my bill what they can do is waive just 25%  and told me to talk with one of their representative from  finance dept so that they will arrange  payment in installment
it is still $1100 i dont know how a F1 student like me gonna pay that much money... is their any way to get out from this problem?
