Barely trained, meaning little knowledge or technical skills to resolve customers problems,full fibre installation problematic from day one, engineers miss multiple appointments when they do install it ,bad workmanship no line test undertaken, talktalk router useless combined with engineers not doing a line test,takes weeks to get sorted as customers services do not have the technical skills to fix it,you will spend hours on phone text live chat,being put on hold pushed to different departments asked non essential meaningless questions that make no sense, if you would like 6 weeks of living hell,with no internet and little hope of getting it ,then talktalk is for you.....
