Vodacom Home Fibre support is USELESS!!!!!!

Every month I seem to get an issue with the Vodacom LTE Router. Yes the router we using is temporary solution that was provided to our company by our telecoms company when we switch to VOIP system last year January, as we were waiting for fibre to be installed. Due to Covid we have not had the fibre installed yet. My problem is basically that certain sites are not accessible and emails cannot be sent or received. Generally I phone Vodacom Home Fibre support and they push a few buttons and it goes back to normal. This time I have phoned the support and have had no success in getting my problem sorted. When I give the MAC address it cannot be found on the system which has not been a problem in the past. I give a serial number the person finds that except on 05/06/2021 the person could not even locate that on the system. Anyway a few buttons are pushed and nothing happens. On my 1st phone call made on 29/05/2021, the individual tried various options and no success, I was then promised a call on the 30/05/21, that never happened. On 31/05/21 I made another call, same rigmarole, no success. I was promised a call back at 10am nothing. On 01/06/21 I contacted again and asked to speak to a supervisor, he checked his system, no record of my calls or any details of my issue, was told it would be escalated. I put the phone down in frustration. I handed over the issue to my telecoms company and they have been just as useless as Vodacom in solving this problem. On Thursday 03/06/21 I contacted the support AGAIN, I requested the individual to get an individual from second line support to contact me, I am still waiting my call 2 days later. On 05/06/21 trying to remain calm I contacted support again, when I gave details the person could not find the router details, so I cut the call. A week later my problem is still not solved. This shows you high level of incompetency that exists in the Vodacom Home Fibre Support and lack of customer care displayed by the staff. I have reached a point where I am looking at simply throwing the router and ****le in the bin and approaching MTN . This problem is costing us money as we have to use cell phones as hotspots to work on emails, so we are having to buy additional data.
