Training gaps/Communication failures - Bad service from Vodacom

We had fiber installed on the 6th April. They attached a Nokia router however the week before a Vodafone router was delivered. We were told that the Vodafone router was not what they normally use so he used the Nokia router. Instead of it being an easy process where my WiFi was activated to date we are struggling to have vodacom activate the WiFi for us! I have called them every single day since the 6th April and have spoken to 4 different consultants every day. Every person says they are “escalating” the query however when I call back the next consultant has no idea what I’m taking about - there seems to be a lack of communication and process failures. I ask each person for the recording of the previous person and nobody has any idea what the previous call was about. I have no idea what to do to get my WiFi activated as every single consultant I have spoken too does not know what to do. I’m not sure if there is a big training gap or if nobody wants to assist us in sorting our WiFi out - however when the sales team wanted us to take the contract out they were more than willing to assist but Vodacom can’t complete this process in its entirety. Extremely disappointing service.
