Disappointed customer

I have been with the provider for more than 4 years, two days ago they had maintenance and after this we have no internet. No feedback from the company about what's happening. They just left everything as is and couldn't be bothered about sorting the network out. I have recommended so many people to them and this is the type of service we get as customers 😒 😠 I am very disappointed with 123 net, I have sent numerous *** and no reply. Terrified about the type of service they are doing and will not recommend anyone to use them in future.
