Pathetic LTE connectivity

Your service is pathetic - I have 3 devices, spoke to 4 different people on your customer service and the phone was put down in my ear. None if my 3 devices work on data. I have been through troubleshooting the connection settings a million times and still nothing. It was PERFECTLY 3 days ago and since yesterday NOTHING. All data is intermitted and unstable. You have partnered with Vodacom and now NOTHING works!!!!!
