London, April 24 : A new survey has revealed that mobile phone customers in the UK consider the services provided by Vodafone and Orange to be least "satisfactory".

The two companies scored the poorest in respect of both pay-as-you-go deals and pay-monthly options.

T-Mobile was another company whose pay-as-you-go service failed to impress cell phone users, revealed the survey.

Tesco emerged as the most satisfactory provider of the pay-as-you-go service, with a 70 per cent satisfaction rate.

Sixty-seven per cent of the people surveyed said that they were happy with Virgin's pay-monthly contracts.

The survey report by 'Which?', however, says that the entire mobile service sector needs a shake-up when it comes to cost of calls, response to queries, clarity, accuracy of bills, and range of handsets.

"Without one mobile phone service awarded a Best Buy in our survey, the industry has catching up to do when it comes to meeting its customers expectations," British tabloid The Sun quoted the consumer group's online editor Jess Ross as saying.
