I just wondering , how can this type of mistake possible? I think fee are automatically being charged right. This is such huge huge mistake ever , I can't even imagine if that was me. Pheww. Looking at current btc price and 15 btc as fee. I'm going to shop and buy myself a rope. LoL !
Epic blunder. There should exist some chargeback function for fee blunders.
As long as it only returns the fees to the sender for a specific amount and still left the required minimum fees then it's fine otherwise if the thing works like PayPal's chargeback it might be a bad idea.
And unfortunately it seem that this feature is just never be implemented into bitcoin though, just my 2 cents
