The customer service performance of BT, TalkTalk and Vodafone have all been singled out for criticism in a new report from consumer watchdog Which?.
The survey covered 100 of the biggest brands in the UK, in a variety of industries, with the highest rated company for customer service being handmade cosmetics firm Lush with 89%.
Despite recent efforts to improve performance, telecoms firms largely dominated the bottom of the table, with Vodafone scoring 66%, just ahead of TalkTalk (64%) and BT (62%), while energy firm Scottish Power finished bottom of the pile with 59 per cent.
The poll, which canvassed the opinions of 3,501 customers during May 2015, found non-UK call centres (46%), automated telephone systems (36%) and being passed around through various departments (32%) were the main bugbears for consumers
Richard Lloyd, Which? Executive Director, said: “Call centres and telephone systems are the biggest customer service gripes by far.
"Firms need to up their game, those that don’t give customers the care and attention they deserve risk losing out to their competitors.”
