********* and poor service

I owed MTN an amount of R811 which the company was allocated to collect. Immediately when I received the text from MTN to warn me about the account being handed over, I made contact with Nudebt to settle the account. They took two days to respond to my request for payment arrangements. When I finally got thier details, I made a payment immediately. I then asked for a paid up letter upon the reflection of the funds on thier side. I left my email address in hopes of getting the letter in three days as promised. It has been two weeks and three days since the last time I had contact with them. My account is still in arrears and no one knows what they're doing at that collection company. I suggest MTN to move thier business elsewhere as I cannot understand why such a reputable company like theirs is even in dealings with the likes of Nudebt
