I hate credit cards...

So, my credit card company wants to talk to me about "unusual activity" on my card, which I can only assume means use in the UK. I excplicitly informed my credit card company that I was going to be studying in the UK in the next year on MORE THAN ONE OCCASION, but clearly they weren't listening... Here's the fun part- I have to pay to make phone calls in my room and I pay that with MY CREDIT CARD! The UK phone number they gave me is inoperational, and I can't afford to call the US number because I can't buy more minutes for my phone because I CAN'T USE MY CREDIT CARD. There is a solution- I pay cash for a top-up card in Cornwall House, which is what I'm gonna do, but the whole thing is really annoying... On the plus side, between this and laundry I should be able to make a serious dent in my giant pile of UK change... I've got piles of 2 pence pieces, but nothing in this country has cost tuppence since 1905...
