Absolutely god awful! Their customer service is horrendous and disgusting! At first, the issue with my connection was Openreach removing my golden NAD key and giving it to a neighbour in a duplicate address mix up. TALKTALK had no clue how to deal with this. The ISP is supposed to contact Openreach on your behalf to solve any issues with their infrastructure instead, they messed around with line checks and even gave me an internal number for Openreach that got me shouted at by an Openreach employee stating they shouldn't have done that and they only deal with companies and ISPs. A lady in Talktalk advised me to cancel my service and reorder to fix the issue. This failed due to the guy cancelling my service not cancelling properly. He just disconnected the service and left the unusable account live so I couldn't use my details to open a new order. Twice a reorder came to the same error and no one was helpful. On hold for hours at a time and their Live Chat people are mostly rude and disgusting. Round and round in circles claiming their systems can't do this or that and they transfer you to other departments which takes forever. Sent to wrong departments and 2 formal complaints closed without resolution. The second complaint was closed without them even contacting me at all! This company is atrocious and should actually be banned from being a consumer service. Their agents are very rude, incompetent and inept. I wouldn't trust them to proof read the alphabet, nevermind help with issues and faults as a communications provider. They are useless. I finally found a way to contact Openreach myself and get my gold NAD key back so I can have an FTTP service with BT instead. TALKTALK will not help you with anything. They will just make you go round and round jn circles, hang up on you and claim to phone you back when they don't. Never again. You're all useless. I fear a Live Chat supervisor, Edward, lied to me and my month's bill will not be delivered by cheque to me. I think they've stolen it. They promised compensation but I never got any. Unacceptable.
