DSV have xenophobic delivery policies

DSV have HORRIBLE rules to delivery. I am a foreigner, I've been in South Africa for 9 years, I have a work permit, I have a South African husband, yet DSV treated me like less than an ******* alien. I upgraded my contract with MTN (I've been a customer since 2012), and when they, DSV, phone me to deliver they refused because I don't have a South African ID. It is not enough for them that I have a work permit, they demand that I go to Home Affairs and get a letter for them. Following this disgusting conversation, I went to MTN where they kept me on the phone for 1hour and no solution at the end. The following day my husband phoned DSV and with a very bad attitude they told him that is not their problem, they have sent back the phone to MTN. So here I am, paying for a phone that I don't have and feeling just terrible to be treated like this. MTN says they accept passports as proof or identity. I can't help but feel DISCRIMINATED by DSV.
