Incredibly poor service from Mweb

On 29 August 2023, I contacted MWeb sales, requesting that my Vumatel Fibre service be terminated and replaced by a less costly MTN LTE Service. Order # X***3. The order was placed with my router & Sim being delivered on 4 September. Tracking the process online, MWeb showed the LTE service as being installed and ACTIVE on 4/9/23 I light of this, I subsequently disconnected my Fibre router o 5/9/23 and began using the LTE service exclusively. On 15/9/23, I discover that I have no internet service, and when contacting MWeb, I am suddenly informed that my LTE service has not yet been activated? Yet, their website shows it was activated on the 4th already, and, HOW on earth did I manage to use the LTE service for 10 days if it was not activated? I was then also informed that it will take a further 48 to 72 hrs to sort out this disaster. Well, we are now heading for 96 hrs and still no progress. It has now been 15 days since my router was delivered and connected and STILL my LTE service does not work!!! Please MWeb, can you PLEASE get your act together.
