Directors too busy for their customers

I have a credit card with nedbank now for more than 10 years I have always been a loyal customer except for the last year Been said after struggled I was surprised and pleased when I was called by nedbank saying they want to help me with the account The lady said she can restructure my account to bring it up to date At that moment I said I am going to think about it She then called me back and said I can pay 1100 per month and no arrears I thought great nedbank you are really going the extra mile Than the shock came...In the December I start to received calls that my account is in arrears I first ignored it.but than the calls and messages got more threatening about sherrifs will call at my place I than decided to contact the director and as usual I was refused to speak A junio8 with the name Vernon Scheepers got Involved and his feedback no trace of the arrangement I than got hold of MR Brown email address but he is too busy to get involved...wow but part of his salary comes from me..His junior Lebo keeps on telling me that he will not get involved and they can't trace the recordings I mailed the rest of the Nedbank directors but no one is interested in their customers I am not crazy by saying nedbank made an arrangement with me I requested all recordings of calls made to me..but nothing so far
