Poor customer service

I tried to apply for credit card on the 07th May, and i was told that i need debt counselling certificate with debt busters. Debt busters confirmed that its been 12years not using their services and my status is on H and my credit profile is very clear- no debt counselling, debt review, judgement etc.... i even phoned NCR to confirmed that my credit profile is clear i don't even any debts. I even went the extra mile to check my profile on ITC, credit score and experience it is very very good. I need to understand why African Bank is giving me turf time???? i mean even NCR back me up on my credit profile. You retreat me like a ********, hooligan, i have never felt like this **** in my life cause i know i am honest and don't run away from my obligations. Why do you treat me like a piece of ****??? it is a very bad habit if this your way to eliminate people rendering your services. I am utterly disgusted. I have app**** for a credit before and was approved. I will not even recommend anyone to you. Please stop treating me like an animal, stop this nonsense!!!!
