Settlement Letter

I have been trying and trying any and all numbers for a while now, yet no one answers - even though I am out the country I STILL TRY CONTACT TO MAKE THIS EASIER FOR EVERYONE!!! Was constantly bothered day in and day out about my MTN account - even while I was at work, politely asked that I could be called back later, but shortly after that bothered again, not giving any consideration that just because I had a problem with one account DOES NOT MEAN I DONT WORK AS WELL. So now when I try settle this problem, NO ONE can be reached, I guess the interest rate over time for the company is worth more when payments are dragged out. So I'm hoping maybe one day I will be contacted, as I have seen multiple complaints here already. So when they ready to get paid, even just an email would be appreciated.
