I have been trying to leave TalkTalk since mid-December in order to transfer to another, cheaper deal with another service provider. During the transfer process, it emerged that the address on my account (our property address/postcode was changed by the GPO this year) now mismatched the new address details (even although the house name remained the same). It has now taken 17 days to date and there has been no apparent progress from Talk Talk. I have to date sent over nine hours of telephone/webchat time in an effort to get the details changed. I have during that time been accused of an inability to read my own computer screen! I registered a complaint with the company on 14 January which has to date not been pursued by them. I have found their "support staff" and "customer relations" staff unhelpful and accusatory. Their management processes, all seemingly routed through a South African support structure, make Byzantine bureaucracy straightforward. Do not be tempted by pennies off: should anything go wrong in one's TalkTalk experience (and that seems entirely likely, judged by our experiences with them), one will waste pounds of time, effort and energy with them. Avoid at all costs.
