What a joke

At the end of November Vumatel contacted me and said they needed to come change my ONT device as they have taken over the network in our area. Up to that point I was very happy with my Frogfoot connection which worked perfectly. Since they changed the device I have had no internet. I contacted my ISP Greencom who said that thry would sort it out. I went on holiday expecting everything to be sorted out by the time i got back. Upon my return 2 weeks later I discovered that the internet was still not connected. I called Vumatel and discovered they had no record of my ONT and there was no ticket created by Greencom. I created a ticket and two days later a technician rocked up unaanouced so I wasn't home. My daughter informed me that the technician said the ONT device was fine and that it needed to be configured by Britelink. It has been 5 days now since this has happened. I have spoken to both managers called Karabo who never bothered to come back to me. There are no managers to talk to on the weekends. I have since phone and spoken to 4 "Vuma Hetos" ?. All they can tell me is that have escalated it with Britelink. The last lady was supposed to call me back as the line was bad but she never did. From having a perfectly working internet connection I have now been without internet for a month and there doesn't seem to be any end in sight. The biggest confusion is that I don't understand how Vumatel and Britelink are still in business. It's a pity I don't have an option to use another fibre network provider. If I could give less than 1 star I wouldn't hesitate. What's pathetic service.
