Please send revised final statement

I am shocked to have received another phone call today from a person calling herself Mbathu, demanding payment! You sent me a letter, I settled the amount in question in good time, I even received a SMS thanking me for my payment! This can only mean that the amount to be reversed have not been done, otherwise why did I get this telephone call.<br> Please send me a statement as previously requested, showing that it is now all paid up.<br> May I suggest that staff must stop harassing customers who have paid, possibly they lack training? They are wasting money and time on unneccessary phone calls.<br> In future I will not take any further phone calls, only written correspondence will be accepted. <br> I await my statement.<br> Anthony Davies.
