Cancellation Letter request!!

In June 2015, I sold my property and it was registered with new owner. I then called Standard Bank call centre and spoke to a lady called, Santana, with regards to having a cancellation letter sent to me and to the credit bureau as I had sold the property which used to be under Standard Bank.<br> On 1 July 2015, I emailed Standard Bank on the same issue and was given reference number: ***<br> Their contact centre have emailed the Standard Bank Legal Department on more than 3x occasions and no one has responded to provide me with this cancellation letter.<br> Nor has the credit bureaus been advised that the debt has been settled and I no longer owe Standard Bank.<br> All I get given is the run around to contact Standard Bank who never answer the calls.
