Incompetence customer service affected my credit score

MTN South Africa contracts services seem to be going down the drain and their incompetence is now affecting my credit score, I app**** for 2 contract phones online which a consultant advised where both approved, while following up on the delivery on the 10th business day, I was advised that the 1 contract was canceled by the system and in attempts to get assistance the consultant advised that in order to have everything sorted out quickly, I should go to the store.

I had an application done at Jabulani mall and the consultant kept on making multiple applications and now I am no longer able to get the contracts due to my credit score being affected by the multiple applications.

As an existing MTN I'm extremely disappointed and dissatisfied with the service I have received.
