Standard Bank *****s Up Again!

I had a Bluebean credit card with Standard Bank that was settled and closed 3 or 4 years ago, but I only now find out that they had never removed me from a negative credit listing with the credit bureau. So now, in an attempt to get this cleared, I phoned Standard Bank to fix this mistake. They informed me that they will fix and get back to me. A month later, I phoned again and was told that I have to phone the Credit Bureau directly to find out if it was cleared. I refused and said that this was the Bank's mistake, they need to fix it and report back to me, again they said they will sort it out. Now, another month later, I need proof that it was sorted out. So, I phone the bank, who once again informs me that that I need to phone the Credit Bureau to see if it has been cleared. So, upon phoning the Credit Bureau, I am informed by them that the listing is still reflecting on my credit report with nothing received from Standard Bank to clear and update their records. So, to this day, a credit card settled and closed 4 years ago has still not been cleared by Standard Bank. This is absolutely ridiculous! The service from this bank is pathetic!
