Vumatel deserves a very bad rating

I used to be an admirer of Vumatel when they started. However they are now absolutely terrible. Many subscribers to their fibre work from home, and are completely reliant on good internet. However when a problem occurs it can take well over a week for Vumatel to sort it out. You are also not allowed to contact them directly, and have to work through your ISP. My ISP says they also cannot contact Vumatel directly and talk to someone. This week they have been up and down for sometimes over half a day. They did sy last week that there might beb some disruptions this week, but it has been chaos. I have lost a lot of money as I give on-line courses to professional engineers during the week and have had to cancel some. It is absolutely disgraceful.. I think they need a thorough management shakeup, and should realise they are now an essential service.
