Clueless and useless staff

MTN Oakfield staff are firstly clueless about MTN services, bias and are selling us sim cards that are not working!! Since the 25th of February 2021 to date, my cellphone has not been working because of a malfunctioning sim card they sold me. They have been making excuses about the Port department and Rica being offline, however I spoke directly to the port department who have confirmed that the port was successful including the Rica last week Thursday already. The issue is with the sim card.

I went to Oakfield yesterday and they closed the door on my face after I told them they sold me a malfunctioning sim and was told to come back the following day. Imagine how indecent they are, after being made aware of their mistake, they tell me to come back tomorrow after 7 days of not having a working sim card... MTN SA please do something about this situation!!!
