Intermittent broadband and noisy phone line

Hi,

I have been with talktalk since and not had any issues with my fibre broadband or phone. A couple of weeks ago the internet has start to drop it's connection and the phone line is very noisy with a sort of static and crackly sound.

I have also got tv boosts and the internet issues are effecting those channels and making them unwatchable.

I have tried switching everything off and reconnecting several times but no joy. I have had to post this from my mobile as the broadband can't seem to hold a connection long enough.

Any help would be great.

Thanks
Dan
