Received horrific cheap product in the mail, called asking what address to return to and they said we couldn't return them? Then we receive a invoice for $236!!! For plastic? After a month we receive a threatening call from a "bounty hunter" whom claims he's coming to our home and is collecting the money for Ace. Continues to threaten and harass until invoice was paid for a product we'd been told we could return until we actually wanted to! This company is an absolute SCAM!
