Frustrated small business

4 months ago my company app**** for an overdraft increase of R50,000.I was told by the small business manager,that the credit department needed the financials to proceed with the application,this was done which costed my company,then few weeks thereafter was told they needed a cash flow projection,which was done and submitted.Few weeks thereafter after several calls and visits to the bank,also getting hold of the regional manager, the overdraft was approved as a temporary limit,but was given for two weeks and taken away,till date have not been added to the current overdraft limit,although a new application was done and was assured by the small business manager,that the new limit of R50,000 will be added to the old existing limit.My company has submltted all documents as requested by the credit department and we hold an excellent account with Nedbank.I have have all the correspondence sent to all Nedbank staff urging to bring closure to our overdraft application.Till date nothing has been done ,just passing the buck from one individual to another.The latest was that i must write a letter of motivation to say why i qualify for the R50,000 over-draft,which is absolutely ridiculous.
