Vericred billing nightmare

The most ***********, unhelpful and annoying company I have ever worked for. Got hounded by them after being handed over. Multiple times explained to them I have received no bill (from either Vericredit or Ampath), eventually figured out they had the wrong e-mail for me (probably from Ampath). After paying the Ampath bill, continued to get hounded by them for an outstanding Ampath bill. After checking and getting statements from Ampath twice showing zero balance on my account, eventually got Vericredit to admit this is their bill, not Ampath. I then asked for an invoice so I could pay the outstanding amount. After 4 months of begging them to send me an invoice, finally got it out of them this week. In the mean time they keep sending SMS messages, and running the bill higher and higher, since they bill for ever SMS they send, even after I politely asked them to stop the SMS messages while we are resolving the issue. So according to me, it looks like they will delay sending you the info you need to pay their bills for as long as possible because by delaying this, they can run up a higher bill by sending SMS messages which they charge a huge amount for ... seems they found a nice loophole to increase their billing to their unsuspecting victims, and they take no responsibility for the fact that they had the wrong information on their system, and did not corr3ect the information after being told multiple times that it was wrong, and after having been sent the correct information. Last time I spoke to them my information on their system was still wrong. Such fun sitting for hours wasting time with such incompetence...as if we have nothing else to do with our day.
