Never have continuos service

I have complained for 10 years about the extremely poor DSL speeds and the irregular internet connectivity. They promise and apologise but it never gets any better. I cannot get fibre as it is not in my area. I asked to upgrade to LTE A but true to their poor service, they don't have stock on the 60mb router which would be free if I sign up. Today I have complained again and still don't even have the reference number sms'd to me. This is so beyond pathetic that it's time to change service providers of which I have been loyal customer for more than 15 years. Mweb do not care
