Had CF now for 2yrs. Initially all great. But in the last six months totally changed.
GGNAT - Well documented, but I can work around that as needed.

Very unreliable connection, over-contented with huge speed drops outs during the day and night, packet loss and routing issues in their backhaul which tech-support cannot even understand let alone attempt to resolve for over a month.

Just don’t get me started on billing and admin. Impossible to get a straight answer from anyone, phone calls contradicted by the next person to talk to you, billing changes by 25% randomly with no-one able to resolve without escalation.

New support team and customer service team with a recommendation to "turn it off and on again in five minutes" is their stock answer to everything. Even when you send screenshots of packet loss and routing issues - just ignored.

Whilst I loved the claimed 1Gig service rarely got 300MB during the evenings. Shame used to be great.
