I first put $20 on a calling card with CelticTel.com in Dec 2008. I only call one older relative (she has no email/Skype account) in Ireland at Christmas and her birthday, so a few months will go by before I call again. Inevitably, when I try to make a call it says the "card has expired". It can take a couple of days of phone calls to unexpire it. I was so anxious to make a call in December 2010, I topped off the card again with another $20, just so I could make a call. According to my online account, I made two calls at Christmas, both under $1 in cost. Here I am in June 2011, and my card is again "expired" - even though their website claims that cards don't expire. My account says "$5.75" balance, even though I made less than $2 worth of calls on it, plus there was a few dollars of a balance before I topped it off. There is not supposed to be a monthly fee, but the balance is leaching away. The phone support is pleasant but amatuerish ("leave a message and we'll call you back"). I would not recommend this service. Something is amiss.
