Miss placed my documents and bad attitude

In December i went to Telkom in Clearwater to apply for a Sumsang S6 Edge plus and they advised me that the phone is not on stock but i can leave my details (payslips, bank statement and proof of res and a form that they gave me) when i went back to check the prosses of the application they told me that the phones are still mot available and there only phone that is available was a black I-phone S6 Edge. When i told them that I will take the i-phone they asked for my documents again and I told them that i left my documents in December they just laughed at me (Zodwa Dlamini and Nobantu Mthimkhulu) and said how would they find my diocuments if I left them for so long, from there they just ignored me and called another customer to who happened to be white in color. This is really unacceptable if telkom can not assist me with getting a phone can they please bring my documents so i can apply alsewhere and please tell your staff to have manors and stop acting like Telkom is their own company last time i checked TCF was the number one priority on all the service preoviders I dont know why Telkom staff does not practise that. this is the first complain. I'm awaiting for you responce.
