They've done this to me as well, only I never even requested the line in the first place! Every month I spend an hour or more talking to them, they see the problem, see there's no usage on the line, see there's no device or SIM card attached, and promise they're going to fix it. Then they charge me again, and slap on late fees for the previous month for a charge they said they were taking off. Then I pay my bill the next month, and they not only use that money to once again pay for the line they said they've removed, but also the late fees. So then it becomes a "partial payment", and they slap me with more late fees. I've paid HUNDREDS in dollars in late fees thanks to a number I NEVER EVEN REQUESTED!
This has been going on for almost a year now, and today they tell me that there are no notes on my account to even remove the line. Like I just love paying fpr a line that has a non-existent phone on it.
I have never in my life seen a company as crooked as this. I've seen where they've had to pay out for other scams they've run, and we really need to start a class action lawsuit over this.
