I am registered in applestore Spain and I have .12 Euros left. But now I am in the USA but doesn't allow me to go to US store because of .12 Euros left in account. I need to leave my account in 0

Hi,

I have the following problem. I put a gift card in the Spanish iTunes and still I have 0,12 Euros remaining in my account. Now I want to go to the US store, but I cannot do it until I finish to use my 0,12 Euros. The problem is that my credit card only works in the USA, so there is no way I can change Store and this cause me a lot of problems. In fact I have 50 Gigas in my iCloud which I am loosing because I can not refill my account and probably I will loose my information, pictures etc. I don't mind loosing the 0,12 Euros but there is no way I can leave my account in zero and there is nothing I can buy for this amount. So I really don't know what to do. Please I need help. Thanks
