Re:I Had a Similar Problem (Score 2, Insightful)

I too have T-Mobile in the States. I had a similiar issue where as I had 2 phones on my plan. T-Mobile was nothing but entirely professional with me, able to cut the phone off while talking to them, and turn it back on 8 hours later for no fees, etc... (I actually did suspect my 'Partner') I have a feeling that you definitely did not talk to the CSR properly. Don't try to diagnose the problem for them, simply question the calls that you didn't make. I know from my T-Mobile bills, that each line is split out and detailed by default from T-Mobile, so you should know from looking at it which phone line is in question. If it is your partners' line, you might have to evaluate your trust in your partner and even the people around where your partner would store their phone. But in either case, T-Mobile has never hung up on me, so either you got the wrong Rep or you simply were not talking to them properly. GOOD LUCK !
