When I made my payment with a debit card I was transferred to someone who was going to verify payment. He read me the last 4 digits of my card, which were incorrect. I then corrected him and he said "well the payment went through".
I asked him to repeat the card number that he read so that I could correct it and be done with this "collection".
He then said "well the payment went through"
I asked again.. "well what card number did you just read because I want to make sure.
He says "I don't know what I read"
Are you serious???? What kind of company is this.
So of course I asked "You don't know what you just read????"
And then he says "have a nice day ma'am" and HANGS UP!
Are you kidding me!! After I just made my payment in full, this is the "customer service" that I get?
RIDICULOUS and I really hope they are a legit company for the sake of my identity.
