TalkTalk "free fibre upgrade!" Don't believe it. No communication, received an e-mail from a courier to say "Your TalkTalk delivery is on its way." Hadn't ordered anything or been contacted by them. Turns out it is a new router for the impending "free" upgrade which I wasn't informed of. Fifteen calls and hours of wasted time later have been outright lied to regarding contact prior to an engineer visit (it didn't happen) that my existing phone will work with the new set up (it won't) and that the engineer will be able to replicate the existing set up (no). Engineer turned up, so after he and I spoke to his company to explain the situation he left. Felt sorry for him as asked if this happens often and he said all the time with TalkTalk.
E-mailed their complaints address and received an automated reply inform me of the ways I can contact them! Unfortunately can't leave them without a penalty as still have a long time on my existing contract.
