Syntech/Gizzu don't want to assist with recalled unit

Bought a Gizzu 518W unit that turned out to be 1 of the units that were recalled due to a manufacturing error. Now...I bought it from Cash Converters, who got it from Takealot. Confirmed by Gizzu support. IE. new from the manufacturer it just took another route to get to me. Received an email from "Gizzu support" but now I am blocked from replying. for some reason! Don't see why a recalled unit can't be swapped just because I got it through a different supplier. I am also willing to trade it in for a discount or at the very least I wanted to know where I can have it fixed, but alas: no assistance!
