Unfair Listing on credit record

I had a contract phone with MTN, I was paying every month until I got retrenched from work.<br> Yes I should have informed MTN that I got retrenched, but I didn't because after being retrenched I was able to pay my account every month for the next 5 - 6 months till my finances got really bad.<br> <br> My issue with MTN is that they have Placed a DEFAULT on my credit record without informing me. I complained about that here on Hello Peter before, but they say their records show that the contacted me, yet I have never received any contact whatsoever from them .<br> <br> So I even went to the post office and never found any letter/s they sent me to inform me that they will place a DEFAULT against me.<br> <br> From what I know, no institution/creditor should place any costumer on DEFAULT without a WRITTEN WARNING LETTER.<br> <br> I would really appreciate it if you send me proof that you did send me WRITTEN WARNING/S that I will be placed on DEFAULT.<br> <br> What you did is very unprofessional because you have my Postal Address and House Address yet you failed to send me a WRITTEN WARNING that you plan to place a DEFAULT against me.<br> <br> I hope something gets done to resolve this ASAP. <br> <br> I got a new job and will settle the account.
