Home-Connect poor service

They are my ISP and Vumatel the fibre provider. I have had an issue with intermittent service for the past 7 weeks, first call logged. The support desk personnel are very polite and the phrases I have heard everyday are 'Very sorry about the problem you are having', 'I will add a note to the ticket' and 'will send it to the escalation team'. The support staff are not allowed to put you through to someone more senior. You never get the call back you are told you will get. It is very frustrating to have to repeat the whole saga everyday as you never get the same agent and if you ask to speak to the last one you dealt with they are not available. Very sad when you are paying someone for a service that they are no prepared to sort out an issue when you have one.
