Had a problem with them too before. They would call 5 or 6 times a day when I wasn't home but show up on Caller ID. They finally picked up the phone when I answerd, told them the 'remove me off the list' thing, next month called again, told the lady, no I don't want to switch, etc. and before I could say remove me off the list she hung up on me.
The next month when they called again I told the guy I would NEVER do business with them since that one lady hung up on me, he said he would take me off the calling list, and THANK GOD they never called back again, been 8 months since.
I'll still will never do business with them again.
