Talk Talk.....bringing back a few painful memories. Had broadband with Bulldog (great service) who got bought out by Pipex (ditto), who got bought out by TT t/a Tiscali....who managed to downgrade my 16mb connection to 8mb within a matter of days and when I complained failed to do anything about it, time and again, except giving me scripted email answers. Cancelled my account (no attempt to keep my business nor an apology), went to O2 (who were great in five years of service). Tiscali then tried to bill me for two months service despite the account having been closed and the phone line transferred back to BT (so I couldn't use any of their services even had I wanted to). Took months and complaints to first ISPA (service providers' association) and CISAS (independent adjudicator for telecoms disputes) to get them off my back.
