TT Connect lousy

Had my fibre installed at my place on the 6th of September 2018, it’s now the 22nd of September (more than 2 weeks after that installation) and yet I still don’t have access to the internet

Calling in or even writing an email to them is a futile exercise, as their lines always put you on hold, but when you do get through, no one knows how to assist

I’ve explored all avenues to try resolve my issue, which I believe is a minor one, but 2 weeks later I’m still lost as to what to do. I’ve no option but to cancel my subscription with them and would advise anyone considering using TT Connect not to use them
