should I request a refund?

helloo, so i wanted to order a sweater from the UK (I'm from Romania) and the seller said it would be possible and that I could pay through PayPal. I've done this, but since then I haven't heard from them :/ I asked them to tell me whether they already shipped it or not, but I didn't get an answer. Should I wait a bit more or should I request a refund through PayPal?
