MTN PATHETIC SERVICE

I was contacted by MTN in October 2020 to upgrade my contract that was due. After 2 weeks when I didn't get the device as promised, it was said that the agent made an error. I requested them to listen to voice recording which they did and apologised and thereafter said agent no longer worked for them now. Thereafter I got my 1st bill which was almost R1000 more than what I am use to paying. I have been escalating since and empty promises are made to rectify but nothing is done. I pay for this phone for my 78 year old mom which lives in a retirement village. Yesterday the phone has been cut and she has no means of speaking to us. She is in quarantine. She is cut off from making calls and all her data. This is very cruel to the elderly. She has no means of keeping herself busy on FB and more importantly communicating with us ito her medication required etc. MTN has inconvenienced our entire life and making no effort to rectify this mess. How is it possible that after escalations nobody returns your emails. How long does it take to rectify an error MTN has made on your account and then still has the audacity to cut off our phone. I am a longstanding MTN client -and this is how they treat their clients. No respect at all!
