Vodacom Business LTE

I have a Vodacom Business LTE contract which has not been working since 07/12/2020. I have logged numerous calls and have sent emails on a daily basis. The consultants don't even bother to respond or acknowledge my emails or queries. They still bill me on a monthly basis for zero service. You can not even escalate this because no one will route you to a supervisor or manager. All they say they will escalate it for me. I have spent more than 6 times the contract value on data to hot spot my cellphone in order to keep my business running. In total I have emailed vodacom more than 15 times (No response) I have called at least 5 times, every time for about 45 minutes (using my airtime)
