All I wanted to do was to upgrade my residential account to a business account. After 40 minutes of wasted time being passed between SIX departments I was told that this was not possible. When I asked why the reason given was that TalkTalk Business and TalkTalk are separate companies! They have a link to the business web site from the residential site; they share the same name; they are both owned by Carphone Warehouse but you can\'t upgrade to a business account without first closing the account (and paying a ?70 penalty if it\'s before contract end) and starting from scratch. Does makes sense?
