International Bolt On Calls

[BD1234]

I purchased the International Bolt on for £3.
This states that calls to the USA will be charged at 2p/min.

I called my friend for a total of 4:10:15 and I’ve been charged £350+ which indicates I’ve been charged £1.40/min instead.

I’ve spoken to O2 live chat for help and assistance and at first they said it’s because I have made the call whilst on holiday. I said I was at home so they checked and confirmed the call was made in GB. 
They then said oh it’s actually because the calls were made on a special number and that’s not covered in the Bolt on.

I used my standard Pay Monthly personal phone number to make the call. And my friend has a standard American number. Neither of these are special or premium numbers.

So confused and do not have the funds available to pay a £350 bill when it’s O2s mistake!!
