Complex, Worse, Slower

Opened a Prestige Cheque Acc in 2015 and lost my job the same year. During this time, the monthly fees have been accumulating on my account and I could not close the account as I had to first pay the service fees. Just service fees, no OD,Or loan etc. I was contacted by Nimbles Collections in October last year and immediately wrote back to them on 27/10/2016 with a proposal, there was no response from Nimbles. Again I wrote to them on 04/01/2016, no response again. I then called Nimbles. I was advised that the account is no longer with them but gone back to Std Bank. I was given a number ***. Std Bank then advised that the account is now gone to Vertex Solutions. So I called Vertex on 19/01/2016 and asked to speak to the Manager. I explained the whole story to now the 3rd company handling this and was asked by Vertex to send a copy of my retrenchment letter. I immediately forwarded the correspondence between Nimbles and myself as well as the requested letter. Still waiting for a response, I cannot close the account, am not employed and the fees keep piling up for no services rendered. I have now been listed as a slow payer by Std Bank and its affecting job credit checks.
