Home-Disconnect. Permanently!!

A week and a half ago I submitted a change of address on their website. To-date, I still have no WiFi. A consultant called me stating they have no change on their side and I must have not done the application correctly. After back and forth phone calls and arguments, I have requested a refund but was advised that they will see ''IF'' they can refund me! and If I cancel and go to another service provider, I will have other costs incurred to me! Their whatsapp communication is terrible and they never call back when they say they will. I have now resorted to going to their actual offices as over the phone service is shocking!! Their Wifi is outstanding but their service and attitude is disgusting!!
