AVOID at all costs. Upgrading within talktalk package from old copper line to new full fibre line. despite being live for multiple days they claim that my new package is not active and not only did they not bill me at the old rate, but came up with a random new higher rate. Would not address this issue unless I specifically plug in a specific router provided by them to 'prove' the line is active. Told them their router is not being used because it has connectivity issues. When challenged what relevance which router I am using is to my billing, they just say it is a only way they will address my billing issue. The new package uses a completely different modem and outside cable than the old one. Confirmed my old line was not working anymore and new one is working, provided photos of the new modem with lights showing working, even using the internet provided by the new line to leave this review and check on account details, yet talktalk still claim my new package is not active so they cannot deal with my account inconsistencies.
