I want my man back

I app**** for home connect router and made upfront payment of R600+, the lady who was signing me up gave me false information now they can not deliver the router because I'm in a process of receiving my smart card ID while the lady told me I can provide ID copy to the driver only to find out they need actual ID, I contacted MTN to change delivery method they don't assist instead they give me another of which when I call they tell me they can not assist with delivery, sales department has to do it but when I asked to transferred to that department they tell me they can't transfer calls. I went to an MNT store they also didn't help because I app**** online
