Vodacom unacceptable service

We purchased an LTE router last year and we have never had any LTE services even though our area is advertised as an LTE area. The connection has always been problematic with low speeds. But since lockdown started, it's been worse with little to no connection. Since Vodacom is in breach of contract, we have requested to cancel this service with no obligation from our side to pay a penalty however Vodacom will not accommodate us. They are robbing us since we pay monthly for a service that they cannot supply. When trying to get into contact with them, the calls get dropped and one cannot speak to anyone of higher authority in the company due to "social distancing". This is unacceptable and really frustrating since we need to be able to work from home. We have to buy additional data to use off our phones due to this service that is not being supp****. Vodacom doesn't not call back when they say they will and they mark issues as resolved when they have not been resolved. Don't get a contract with Vodacom.
