Really sorry to hear you're having trouble with your service.
I've located your account and I can see an issue with the network in your area affecting speed at peak times - Ref.(F004079900). Our technicians are looking to get this sorted and have set a review date of 29th March.
I've also picked up an issue with your Downstream Power levels that will need to be adjusted by a technician. I've sent you a private message (purple envelope at the top right of your screen) so I can arrange for a technician to adjust your levels and take a look at the hub.
