unsatisfactory rejection reason

I recently tried to get a contract for a Samsang S6. after filling in the forms i could not get the phone because the phone's serial number was not agreeing with what was on the system. i was told i would get another phone the coming week. i then got a call saying that my salary was too high so it was denied. whilst i was still in shock i got another call saying that my ID number was foreign and could not be accepted. well this is my SA ID i got from home affairs because i have permanent residence permit. i have been using this ID so many many times and it is a south african ID though i am foreign. i tried explaining this but it proved to be rocket science. after that i then got another call saying head office had declined my contract because of my credit rating. Really?????? it is as perfect as a baby's smile. telkom should put professional people who evaulate contract applications and know exactly what they are saying. whoever it was who was verifying at head office showed no understanding of the process. and whoever it was did it representing Telkom so to me this is the kind of professionalism you get from Telkom. VERY POOR.
