MTN service - non existent

Hi, I have been struggling to get assistance from MTN for the past few months. Firstly, we have a fibre line with them for which we were being overcharged for over a year. It took hours of phone calls and being sent from pillar to post to finally get this resolved. I then logged a request with them on 7 July (once again after numerous phone calls, WhatsApp messages to their WhatsApp line etc) for a VOIP line to be installed. I have been following up daily for the past 2 weeks and I get the same feedback everyday. The request is with the project management office and they can’t do anything about it. It boggles my mind that they are so resistant to taking on new business in the current economic climate. It seemed like a mammoth task to change our fibre line to a different service provider and get a VOIP line through them, however, considering the amount of time I have spent begging MTN staff to assist me with this new request, it probably would have taken far less time to engage with a new service provider. MTN service is non-existent. Staff refuse to put you through to a supervisor or someone who is able to assist. It seems I will now be forced to change my fibre supplier as MTN is clearly not interested in new business or looking after their existing customers either.
