A couple have been told they must pay a bill of more than £8,000 run up by thieves after their mobile phone was stolen in South Africa.
Calls were made to Pakistan, Qatar, Senegal and Ethiopia
Zyg and Rosemary Gregorek, who own a fishing complex at Halwill near Holsworthy, Devon, were on holiday when the phone was stolen in Johannesburg.
They only realised it was missing when they got back to Britain.
T-Mobile says it is extremely unlikely to waive the bill which shows the phone was used non-stop every minute for a week, with calls to countries such as Pakistan, Qatar, Senegal and Ethiopia.
T-Mobile initially sent the couple a bill for £1,300, but that increased to £8,115.29 when the firm included the full list sent from South Africa.
The phone was cut off when the company became suspicious of the huge increase in calls, several days before the couple reported it missing.
But Mr Gregorek, 40, says his holiday insurance will not cover the cost and he is appealing to T-Mobile to reduce the bill.
He said: "We are devastated. We can't afford that kind of money. We are not destitute, but it's beyond our means."
Upsurge in calls
Mr Gregorek criticised T-Mobile for not spotting the upsurge in phone calls and cutting off the line sooner.
"My wife's bill has never been more than £15 per month and they are aware of that.
"It was completely irresponsible of them to let the bill run up as much as it did."
Patrick Barrow, head of external communications at T-Mobile, said: "The contracts are very, very clear that up to and until the point where a customer reports the phone stolen, they are liable for any expenditure run up," he said.
"We stand by the fact that this couple have to pay.
"We will look at the best way to approach this, but we won't waive the bill."
