account paid up but still not reflecting

My name is cynthia phalama,I settled my vodacom account on the 28th november 2014 and it was not reflecting on their side,then I was advised to send through a letter from the bank showing that I have indeed paid!the letter was sent to george from finance department who said he will get back to me as soon as they sort everything out, until today the matter is still not resolved and I'm getting endless calls from VVM attorneys telling me that I owe money on an account that I have settled and closed a long time ago.<br> I feel harrased because on the phone calls and I can not get financing on anything because of this matter.
