Cant get any Telkom products

Good day, I recently sent a form to Telkom as I was interested in their January R599 special deal. I also sent in a request for the R799 smartbroadband uncapped deal. They phoned me and said unfortunately my area doesn't qualify for the R799 uncapped deal. So I said I want to take the R599 deal. She took all my details, banking details and said I qualify for the deal. An hour later I receive and email to say Dear Telkom customer, Thank you for your online application. Unfortunately your application has been declined during our initial pre-vetting stage??? I don't have any bad credit so why should I be declined? So I am not allowed to now purchase any Telkom products. Tried to phone the Bloemfontein branch a few times and the phone just rings, its impossible to get an answer. Really bad service!
