Bad customer service

I app**** for an account at Mr Price sometime in May 2018.it was declined and the reason being that i didnt have a hard copy of the work permit as a foreigner. Well i was still waiing for the permit. So they said after 3months when i get the permit i must re apply. I then applid again last week, with the work permit. Again it was declined. On calling them to know why it was declined this time again the reason i got wasnt valid. This Buyi girl really doesnt know her work. She says i did not meet the scoring criteria. I wanted her to explain wat it means, the she says it means the system did not pick up that i have an other account with other retailors. Well i told her i have an account with Foschin for more than 6years now and i have contract with MTN for more than 6years. Evenbthe bank account with Standard bank again. She says to me well their system didnt pick it up. Im asking her wats the way forward now. She tells me to re apply after 3months again. Can u believe. Then i asked her then after 3months wat guarantee do i have that the system will pick me up now. She then promised to call me back by monday but up to now i havent got any response Im not pkeased at al how the Mr Price handled me.. If its not for us foreigners for sure they should have said so earlier that to toss me around. Im really not happy. I need an explanation to this
