If you don't receive your item one day after the item's last estimated date for delivery do this:
Go right of the item purchased, and from More Actions select.... I Have Not Received My Item.
If you are not fully refunded within 3 days, you must escalate the case on day 4 or within 30 days from opening the case, and eBay will step in and force the refund.
Do not close the case early for any excuse or promise the seller may give, and do not forget to escalate.
We do not know the reason why their account is blocked, or if it is at all, so ignore any excuse the seller gives, open that case, Do NOT close it for any reason / promise the seller may give and don't forget to escalate.
