Poor service from vodacom fiber backend technical support

My vodacom fibre has been down from the 14 January 2021. Repeated calls to the call centre has had no success. I was told that the technician at the "backend" would resolve the matter but nothing is being done. Thus service is already been paid for and I have no connectivity. I tried the call centre again this morning to cancel my contract and the call agent says that there is no way to transfer me to that department. I asked to speak to a manager and he says that managers are not available! I have been very patient with vodacom but now I've had enough. Another fibre provider has offered to settle any clawback agreements and take me on. If this matter is not resolved ASAP, I will cancel my vodacom account.
