Two in five British consumers have had to make a complaint about a service in the last 12 months, a new Which? survey has revealed.
The most complained about sectors are broadband, mobile phone, and energy services.
Almost one in five broadband and landline customers have made a complaint about their service, with 14% of all mobile phone and energy customers making a complaint, according to the Which? survey of more than 2000 people.
Of all complaints 40% are not resolved by the provider.
Which? executive director, Richard Lloyd, said: ‘It’s incredibly frustrating to get poor service, especially if you’ve had to repeatedly contact a firm or your complaint is passed on from department to department.
‘It’s in every company’s interests, if they want to succeed, to treat their customers properly and provide them with the best possible service.’
If you want to make a complaint to your broadband provider, you can use our step-by-step guide to help you complain about your broadband service.
The top reason given to customers for failing to resolve a complaint was that the problem was outside the service provider’s control (26%).
Other explanations included that another company was responsible (15%), that it wasn’t possible to fix the problem (15%) and that the provider had done what they had promised to do (13%).
Problems not being resolved by the provider were most prevalent in trade services, where 58% of complaints were left unresolved.
Airlines and holiday operators failed to resolve 56% of complaints, while 53% of all car and vehicle repair complaints were also not resolved, according to the survey.
