Poor Service

They told me to Pay EZ4U Capital R1001.00 that I owes and send them POP OR paid up letter, I did and I was told to pay them R4800 for my name to be cleared up. I paid them more that R4800 and they told me that my name will be cleared up once I am done paying them R4800, cause they made me pay it for 3 months as installment. My worry is that when I check my credit score EZ4U Capital still appers that I still owes them. I have been calling them, everytime when I call I get new person. Hahn & Hahn must pay back my money.
