Excellent customer service
Just to add some balance to a lot of the posts complaining about the customer service.
I recently had a couple of minor outages, even though all lights were green on the ONT. May 14th happened overnight and internet was down when I woke up. Contacted support on chat and they reset something remotely and got me back up within 1-2 hours. Same thing happened on may 15th.
Been fine since then so assumed it was resolved, however I asked in the chat if they could see the cause of the outage. A very helpful person (Victoria) could see there was an issue with the ONT itself, and immediately booked an engineer to arrive the next day.
Brilliant service all round, I've been with YF for around 2 years I think now and love the low latency and 2Gb up/down. (And no, I'm not affiliated in any way with YF 😂)
