MTN STAFF NEED TO BE TRAINED NOT LIE TO CUSTOMERS

I have signed up for a new home internet on the 22/11. Till today I did not receive the Makro voucher. Also Thabiso Komane assisted me saying the router works during load shedding and it lasts upto 6 hours. She also said I cannot pay directly I need a debit order. Today I received my statement it says I can pay directly. The fees online shows R499 that's what the sales lady said I will only pay the once of installation and this fee of R499 but the statement shows R548. I receive sms's saying I have free funeral cover but where is my Makro voucher. Whenever I call Mtn I cannot get through. On the 30/11 I received a call from Rowan who advised the router does not work during load shedding and I should wait a few days to receive the Makro voucher. Calls are recorded so why are the sales agents giving different stories.
