Number showing on my Caller ID when I got home.
Caller ID: 3019tm
Caller: ????

I have never had never experienced such a horrible customer service ever before!! Their customer service and technical support is totally stupid, rude and unhelpful, I signed up with them last year and paid 115 dollars as a startup fee, I waited for the adapter for well over 14 days, and it took them 22(!) days to port my number, after this I have been dealing with serious billing errors right from the very first bill and they refuse to understand what they are doing wrong by providing one-time-corrections that only exacerbate things. After 2 months of this terrible experience I decide to cancel, their customer rep. was rude with me, sounded drunk and sleepy, put me on hold for more than 25 minutes and disconnected after that, I tried to call back, but after pressing 3 on the IVR I heard only that the phone was dropped, it was an expensive lesson with them. I asked for them to give me the office address to pay them a visit, but it took them more than 3 minutes to figure out where they are located. After cancelling the service, they continued to charge my card, I had to call the bank to inform about the fraudulent activity, finally I stopped them from stealing money!! My overall opinion: the worst company in the nation, possibly in the world!! Drunk, sleepy robots reading manuals from other countries ARE NOT technical support, so if you want to save your time and money stay away from them
