Chris Bovis, a 26-year-old builder, contacted his phone company when his mobile was cut off without warning, only to be told that he'd be receiving a bill of £8,900 and another of £10,000 for extreme use of internet data.
His phone company Orange attempted to take the bill of £19,000 but the transaction was blocked by his bank, according to the Daily Mail.
Bovis said: "My first reaction was to laugh as I could not believe it."
Restoring the factory settings of the phone and switching it off both had no impact, and the phone continued to send and receive large amounts of internet data.
Apple staff agreed that the phone was faulty. It is thought that the problem was caused by a glitch with the phone itself.
Despite this, Orange said they would still be charging Bovis with a capped bill of £300, and even threatened with him bailiffs.
Orange has since accepted that they were wrong to attempt to try and bill Bovis for the faulty phone and have apologised.
A spokesperson said: "It does appear that this resulted from a fault with his device, and we are happy to reduce the bill to zero as soon as we have received confirmation of the fault from his manufacturer."
