Hi there and thanks for posting. Our prepaid accounts don't have a receipt you can print off. We certainly want you to get the cost covered by your company. Is that the only way they'll coverage the charges? Sorry I don't have an option I can think of that'll get you that.
I am in the same sort of boat but with the German tax authorities. I live in Germany but have a US T-Mobile pay as you go account for when I travel to the US for work. The tax authorities will not accept a credit card receipt and will only accept an official invoice from T-Mobile. Without any such invoice I cannot claim any of this as an expense/tax deduction.
