T-Mobile finally fucked me

After being a super satisfied customer in LA of T Mobile for 4 years, the have finally screwed me last month. One sunday night I was suddenly disconnected without any warning. When I called then I was informed that my bill had crossed the limit of 150$. Which surprised the hell out of me since my automatic payment to them had just gone through a week back. Apparently I exceeded my 1000 text messages and had touched 1500 texts last month. And the charge you 20 cents per text once you go over your limit. Pretty steep i would say.
Now there are two problems with this scenario. I was never warned that I had crossed 1000 texts. When I complained about that the operator lamely told me that I can always access that online or on my phone. Agreed. But who checks that everyday. Even if I do the T-Mobile(or any other company) must warn me about it.
What sucks is that I have been contemplating buying a i-Phone for past one year. I just never did because of the bad reputation of ATT. Everyone portrayed them as some kind of monster. And I was quite happy with T-Mobile. Maybe I would get a Google Phone once they stop being that ugly. They are half-way there. They just need hipper & younger people than Whoopi to be on their commercials.
So maybe in next couple of month I will finally move to iPhone. So long T Mobile.
