E-mail the CEOF Samsung support, I originally paid in full with debit card to purchase the S24U which was like $1400+ w/Tax and shipping, but now for the replacement they are asking for payment in full again, and will refund the payment later once they get the bad phone back and review it, which could take a couple weeks or more per customer support.
This whole thing is leaving a very bad taste in my mouth, probably just going to return the bad phone, and get my money back, not get another one, and be done with Samsung.
