I don't understand why they think calling 55 times a day is going to make you break down and pay them. There's usually a reason people get behind on payments. They need to chill the hell out.
This is Credit One and these people are horrible. Can expect the calls to start around 8:01 am and repeat from several different numbers about every 20 minutes until 8:59 pm. We have tried talking to them but there seems to be a language barrier making it hard to communicate, that is when they talk 90% of the time they just hang up when you answer. You will get calls from IQOR USA and random 800 numbers which are all them. They never leave a message because if they did they wouldn't be able to harass you all day using the phone.
It's Credit One Bank. They are jerks, and have literally been calling me every ten minutes from about ten different numbers because I closed my card with them. It is so bad I've seriously contemplated changing my number.
