Lost connectivity

I have been losing connection since last Friday. A call was logged, but I received NO response. I asked again yesterday WHAT the status is of the call. VOX told me they sent an email / sms. When I asked to please have a copy I was told 'I am unable to screenshot the backend system'. What is the use of having a VOX WhatsApp system then? All my queries just gets closed, without resolving. Today I was told there are 'peek traffic between 6 pm and 11pm'. I could buy another device to add to my current setup. I am already paying for my service. R729 pm. My internet worked for years at my previous ISP. Such a bad idea to have moved to VOX.
