" Declined credit score "

Sharing my poor experience. I app**** for a cellphone contract with MTN on the Monday, Tuesday was a holiday so the agent phoned me on Wednesday. All went well, she asked for my income amount to see if i can afford it, did a credit check, took my account number from which bank I'm banking with and discussed my debit order date, took my delivery addres ect. Was extremely happy with her service and was hanging on the phone for more than 32 minutes of my time , side note - i was at work ( their internet were buffering the whole time ) so this call took forever. Hence i was extremely patient with the lady who helped me. So after the phone call around 30minutes to a hour I got a email saying that my credit check has been declined. What nonsense MTN. After spending such long time, taking my ID number and confidential information where they were surposed to tell me right in the beginning that I'm 'ACTUALLY' declined! Everyone wants to sell phones but YOUR internet were loading/ buffering the whole damn time! Making future clients so discussed before having a contract with you?? Sies man!
