MTN *****

Did an upgrade with MTN in May month. The requested device was an A55,5G. However, I received an A. 35 and an A 25. I called about te incorrect devices an they arranged for the courier to pick up the two devices. Courier supp**** collection slip showing they picked up both devices. I received my A55 after that After the incident, on billing date, I was billed R1200. The upgrade monthly fee was R450. For the past 5 months I have been paying R1200, on the contract and have had the line greyliated on numerous occasions, meaning I can't make out going calls. I have send numerous emails. Made numerous calls and WhatsApp chats but MTN has me running around in circles. Meanwhile my lines are grey listed and my business has been suffering since the incident
