Linteg disrespect clients

We have been without Fibre connection got over 15 hours. I sent a message to Linteg number only for bolt to respond and say there are no consultants online. I then sent a message to Ryan, he read the message and didn't respond, I kept sending messages and he eventually stopped reading them and just ignored. Thus us affected Stamford Close, Jackal creek, the wedge etc. Linteg has no regard for us as clients but we keep paying full amount for service we are not getting.
