Default micro sd stopped working. need advice

Hey guys. So I have a 64gb sandisk ultra micro sd and a note 2. Have had me card in my phone for over a year. Got it may 2013 and stopped working a couple days ago. Would not mount on my phone and kept saying it was empty. I inserted it into my computer and had to format it for it to connect. Thankfully I could recover my photos that were not backed up with free software.

Now the problem. Everyone knows that there are problems with sandisk and samsung phones. Should I carry on using my card or will the problem persist?

I live in the UK and they want me to send the card to take it back to place of purchase which is amazon, but I bought it over a year ago so would they replace it?? or send it to the Czech Republic at my own cost?!?!?
