THIS IS THE WORST SERVICE PROVIDER YOU COULD EVER USE AS THEY GIVE YOU NO SERVICE AT ALL

I have had a Wi-fi contract with Neotel for approx 3 1/2 years now. As long as everything is working it's fine, but once it stops working you get no assistance what so ever. This is the worst service I have ever received from a company. We have been without Wi-Fi now for over three weeks and still nothing is resolved. The keep "resetting" from their side but it only works for a few hours. They keep promising a technician. but nothing happens. They even have the audacity to say we have to pay for the technician, but still nothing. I have explain my husband is on 24 hour call out and that they send the problems through "Whats App" so he has almost lost his job through having no We'Fi. My mother in in hospital in New Zealand and the only contact I have with her is through having Wi'Fi, but still they don't care. If you threaten to stop paying them and go to another provider they still don't care and threaten that you will be liable for the contract. Why must I pay for a service I am not getting?
