Unbelievably bad customer service

Really terrible customer service. I asked for my order to be cancelled and refunded after it taking so long to get to me after Christmas, with no communication of the fact that they close over December break. Eventually got an email reply, and I confirmed I would like the refund, less 15 % processing fee. Next thing I get a delivery notification. I email them again twice saying don't deliver, I want my money back, no email response, and they still delivered. I complained that they delivered and they said take it to the warehouse to get a refund... Seriously!!? I must mission because you can't follow instructions? Then they offered me 10% off my next purchase... I will never be buying from them again. I think there is only 1 person dealing with complaints...
