Do NOT DEAL WITH THIS COMPANY. ok I used the app for a year on my android phone whilst I was abroad and was happy with it. I had left over credits which I thought I could use on my next holiday. Then they introduce a date limit for your credits to be used by, but that expired my credits before my next holiday. So that was money down the pan. If they want to start a date limit it should have applied to new credits sold, not existing ones, so you knew what you were buying. I then bought some more credits for my holiday. Tried to use to send cards, but found the app no longer worked on my phone which is the only bit of kit I travel with. Seems they no longer supported my version of android. But they refuse to give me a refund Just keep quoting a 14 day refund period. I didn't go on holiday and found their app was useless within that 14 days. Duh.. Totally unacceptable.
