Incorrectly Listed on Experian by Std Bank

I was placed in a very embarrassing situation when I went to take out a new cellphone contract only to be declined because Standard Bank has listed me for an account that is in perfect payment order on Experian. This has caused me much humiliation and inconvenience as I have now been running around since Thursday(1 Oct-15) trying to get Std Bank to rectify their error. This is UNACCEPTABLE!!! Why should I, a good paying customer be put through this inconvenience due to Std Bank's incompetence. I have been emailing Janine Govind and have got no positive feedback to date. Is this what customer service is all about???? I expect this to be rectified ASAP as my next step will be the banking ombudsman. I have all the relevant correspondence to substantiate my complaint.
