Cannot get business banking ****le to work and there is NO HELP from Nedbank

For the last 6 months we have been trying to get our business banking ****le to work. I first contacted our banker, someone from Nedbank then contacted us and tried to get the ****le to work by remote logging to my laptop. The person said they would come back to me which they never did. After contacting our banker again I was told to contact Nedbank's call center which I did. I sat online with them for an hour running some tests, afterward they were going to come back to me which they did not. After contacting our banker again I was again told to contact Nedbank's call centre which our IT specialist did. Again they spend some time running tests, again the call center said they would come back to us, which they did not. After contacting our banker again, he said that he cannot assist without a reference number for the call we did to the contact center. I find it pathetic that we as a business client every time have to cal the call center and that not once have they come back to us after stating that they would and that there is no way of tracing who we spoke to!!!! I know of some banks who are actually offering to help you unlike Nedbank, I can only think it is because our business is not significant enough for them to give a ****!
