Worse customer service ever

Visited an MTN store in Pinetown, dealt with the sales person (Ndumiso), he processed my application and then got to bio-metrics stage, the machine couldn't read my thumbs, he then submitted the application, it was declined on bio-metrics, I had an ID ****** in 2012 during hijack and I blocked it with SAFPS and granted a letter with ref numbers, I provided that with my documents, he called the next day to tell me I must come and redo thumbs, I went again, he re-processed the app and there was no feedback from the system and he promised me that he will send an email to ask the HO to look at the app, I have never heard anything from the shop, I do not understand how can the deal decline on bio-metrics because I have done fingerprints at other places including Department of Transport and they passed, I am so devastated and very angry with MTN service, even worse this is a month to month contract, I feel like as a black client I am being ill-treated and discriminated, my score is very good and no bad payment profile, no bad payment history, I want justice here, not that am asking for FREE contract, please intervene here

Thank you
