Vodafone customers in parts of north Norfolk are experiencing 'intermittent' service just two weeks after a major signal blackout.

The problem in the Sheringham area started this weekend and is continuing today (Monday) for some people.

North Norfolk MP Norman Lamb, who is due to meet with a Vodafone boss this week, said it was 'critical' the ongoing problem was resolved.

A Vodafone spokesman said: 'We're sorry some of our customers in Sheringham have experienced intermittent problems. We have engineers on site today investigating this.

'We understand how frustrating this is for our customers but we cannot guarantee a fault-free service as so many factors, including many beyond our control, can affect a mobile communications service.'

She added the communications giant would look to reimburse a proportion of line rental costs for people who have not been able to use the service for three or more days.

Mr Lamb said he would push for compensation during the meeting at Westminster with Paul Morris, Vodafone's UK director of government affairs.

He added: 'It is critically important they [Vodafone] get their act together and provide a reliable service. A lot of people rely heavily on their mobile phone.'

He praised the EDP's Let's Get Connected campaign to improve mobile phone coverage in Norfolk and Suffolk.

Sheringham businessman Paul Richmond, who owns Online Web Marketing, said he could not send or receive emails, calls or texts and was 'annoyed'.

Denise Burke, prospective parliamentary Labour candidate for north Norfolk, said: 'If Vodafone want to hold on to their customers they need to deliver the much needed new technology and improvements they promised me they would implement, deliver faster technology, and improve customer service.'
