You can but you must contact the seller since they are the one selling it. You can also chat shopee support for a possible refund

I have the same dilemma. I ordered from shopee, never received the order and still waiting for my money refund since May 18,2020. I've done 15 follow ups and they replying the same old scripted message

"Thank you for staying online, upon checking since you already request for returned/refund please be informed that all return activities are paused and will resume once the enhanced community quarantine is lifted. Due to a technical issue, the return dates displayed on your Shopee app may not reflect this change, but rest assured that you will be notified once return activities resume po."

God bless for both of us.
