Harrassment after settlement

<p>I am a very dissatisfied customer with the service I have received from African Bank. African bank offered me a discount if I settle the loan with them in full. They gave me this offer on the 27/04/17 and said that the discount applies if I settle by the 31/05/17. I then settled the account with them on the 02/05/17. After ot was settled I have been struggling to get a paid up letter. I kept on calling and was told everytime they will email it to me but the email never arrives. I then get an email from African bank saying that they sold the loan to MBD Inc and that I now have to pay them. After numerous calls to African bank call centre I am told by agents and managers that they can see my settlement payment and that it was handed over after settlement however they are not sure why. After over a month I finally get them to send me a paid up letter. Up until today MBD still harrasses me for this " money I owe".They asked me to send them the paid up letter which I sent to them on 2 occassions. The constant calls and sms's from MBD still haven't stopped. I am really fedup with them now!</p>
