POOR SERVICE AND DOES NOT CARE HOW EFFECTS PEOPLE

I have been trying to get my credit record updated for 1 week now as this was not closed due to a error on STD bank side. Standard bank have resolved all the issues on their side and now have been trying to get this resolved with TransUnion and they have not been any help at all. I have sent them a letter from STD bank and all the documents they have requested from me to confirm that this account was closed and have called STD bank and they have sent the request off to be updated with TransUnion on the 23/09/2015. I have then call back to the TransUnion and all I have been told is that there is nothing that they can do as they have a backlog I am to call back next week. I have tried to speak to Team Leaders today to get this sorted out they just tell the agent what to tell me and then all of a sudden they go into a meeting when I advise that this is not good enough. This is terrible I have advised that this is not my issue that they have a backlog and that that they should have more staff to handle the work if they are not able to cope! This is effecting me getting credit and I am fuming I cannot believe that they just do not care!! THIS IS TERRIBLE SERVICE
