Buyer’s giveaway never sent

What does WhatNot do if you report that a seller has never shipped your giveaway win from a buyer’s giveaway? I won something with a retail value of $300 on 11/24/24 (and I actully only bought something to enter the giveaway) and they have just been giving me the run around. It’s been a month and a half of excuses. If I report them to WhatNot, will they do anything, or am I SOL?
