Poor Vodacom service

Vodacom's poor service I have a business LTE router with Vodacom. Paying for service but not working. This is now 3 months. Did file a complain beginning of last week and still not working properly. Everytime I phone in I get a different person so speak to and they are all incapable to assist me. Reference nr SR*** flying from one to another and problem not fixed. a Technician did visit me on Friday, and router was reset. He was very helpful and friendly, Two days later router go off again. Why are my business pay for a service that are non existing. Problem are the router are not setup correctly on Vodacom's system, They keep on saying it is connected, but I have no secure connection on my side. This morning I am phoning in they transfer me from one persone to the next. Now 20min later still not at the right department. I must speak tot Nelson Chauke, but he is non existing. Vodacom your service need a proper oudit to see if you have capable people to assist paying clients. Please help, I am fed up
