Unbelievably atrocious. Statements like, "void the contract and delete my details," and, "I am no longer a customer of talktalk," are apparently not clear enough to qualify as cancellation (even if you open correspondence with them by registering a complaint and asking them to convince you not to cancel). But they won't tell you this, they'll wait two years, sell off a "debt" to collection agents, and claim they have no evidence of your statements..because they deleted the correspondence, the complaint and the accompanying message chain. Never have I been so glad to be a hoarder of correspondence. Also, appears team members, and team leaders, in the CEO complaints division are unaware of some fairly basic things of great relevance to their work, up to and including talktalks own customer complaints code of practice lol. I'll, eventually, be taking talktalk to court. The lawyer says I should wait for my deadlock letter, head through CISAS, then get talktalk in court to try and defend themselves. I'd describe the lawyers' current attitude as, "laughing all the way to the bank," lol. Do not ever enter in to a contract with talktalk, they will not provide what they promise, they will obfuscate and outright lie, and they will ignore your requests to cancel. Never has a company been so deserving of a negatively starred review.
