Home broadband and phone provider TalkTalk has unsurprisingly come top in a new list of telecoms operators (those with a market share of 5% or more - covering 87% of the market) that have recieved the most complaints. The regulator notes that TalkTalk recieved an average of 1.27 complaints per 1000 customers between its data collection period (October 2010 to February 2011). Meanwhile Three (3) topped the list for mobile / Mobile Broadband operators.

Nobody will be too shocked to find that TalkTalk faired significantly worse than its competition, the operator suffered a number of serious setbacks last year from billing and miss-selling investigations to significant email migration problems.
