WORST CUSTOMER SERVICE IN THE HISTORY OF CUSTOMER SERVICE

WORST CUSTOMER SERVICE IN THE HISTORY OF CUSTOMER SERVICE. I have called, emailed, whatsapped and live chatted with them multiple times to communicate the fact that my account was settled with the original credit provider before it was handed over BUT NO MATTER WHAT I CAN'T GET A RESPONSE FROM THEM. I have provided all the proof BUT THEY JUST KEEP ON BADGERING ME with debt that I do not owe. You need to close my account !! Any fees that you may think I owe you, you can remove, because like I said, my debt was settled before it was handed over !!
