Seller refused to cancel my orders

I know it was one of the biggest holidays of the year in for most sellers and I had actually placed my order ahead of the holiday for it to get here in time for Valentine's Day. Well it didn't ship and after half way through the time a seller has to ship I messaged the seller and he said that they were on holiday and to wait longer. I waited a few more days and he never shipped. I canceled the order citing time reasons, he canceled my request and shipped the item with 5mimutes left in the time he had to respond to the cancel request. He provided me with a tracking that does work. I don't want nor need the product anymore.

I'm assuming my only two options are to open a disput or ask for a 90% refund from the seller?
