Purchased super fibre in sept 2017 guaranteeing 55MB with 61-80MB upload speed. I made untold complaints during the 18 month contract. They sent a basic router first, super router second both not capable of handling the package that I was paying for or faulty. A talk talk engineer VISITED 3 times noticing slow sync speeds then by open reach came 3 times with the 2nd visit installing a master socket which talk talk engineer should have done on my go live date in sept 2017!!! Monitored speeds via the wire my highest I’ve ever seen is 38MB. They breach there own terms and conditions. Don’t complain over the phone customer service is useless. Complain to the CEOs office via letter and his complaints team take over your case. Currently in the resolution stage for compensation.
