seller shipped after i escalated and denied request

Hi all!

I purchased a shirt from a seller on 2/2. The deadline to ship it was 2/20 before a refund. I messaged on 2/19 seller to ask for an update and they told me they hadn't made the shirt yet (it was an embroidered piece) and that they would ship the next day or Monday (which would be past the Depop shipping deadline anyway).

I gave them the benefit of the doubt and waited until EOD Monday before submitting a request for a refund. They ended up shipping on Tuesday and rejecting my request. Should I escalate anyway if the shirt is on it's way? I submitted a request because at this point I didn't even want the shirt anymore.

Any advice is welcom. I'm wondering if I should just eat it and leave a review reflecting this experience.
