Homeconnect service is pathetic

Zero rating if there was an option.My home WiFi was activated yesterday.it worked for few hours and then went off.I logged a query with Homeconnect and was told it will take between 24-72 hours to be resolved.In the meantime I cannot do my business or I must by data which is not cheap either.When i threatened to cancel this one day old contract I am told I must pay installation costs and costs for the router.Why must must I pay for something that on day one I am unable to use.On signing up I took a package which is meant to cover the whole house but what I have been provided it only covers the room where the router is situated.I am told a long story of buying a 10m Ethernet cable in order for the WiFi to cover other area in the house. I am so upset with Homeconnect.Their turnaround time is shocking
