4 days is meaningless.  You can buy 50cent hacked accounts that work for a month.  You can even get a month for free. 4 MONTHS would mean something not 4 days.  Guaranteed you will be shut down sooner rather than later.  Then try to redeem your "warranty" and see how far it gets you.  Wait 3 or 4 months then see what happens to your eBay account.  Unfortunately users can't change feedback which they have left 2 or 3 months from now after their accounts die.
