An electrician and his wife had a shock when they received a mobile phone bill for £163,000, then fought for months to have the debt cleared.

For 15 years, Alan and Carolyn Mazkouri, from Swansea, had a business deal with Orange for 10 phones.

They told the BBC's Watchdog programme that they normally had a bill for £300 a month, before the shock demand came in September.

Orange has now apologised and promised a refund and a gesture of goodwill.

BBC Watchdog investigated.
