No service, unprofessional, very disappointing

More than a month after my initial request for assistance, due to my line speed not being what I have subscribed for, I have still not had resolution to this issue. They delivered a new router 2 weeks ago, but I cannot get anyone to come and install. I do not get responses to emails or website enquiries. Calls take up to 30 minutes to get answered, after waiting on hold, with no adequate response. Managers do not respond either.
