moldy tasting beef wellington

I am with the rest of the gang -- this does not sound right. Even if the ingredients are OK, then the flavor profile is messed up, and I do not think it is an excuse either. Wellington is a well defined traditional dish, so it should taste like Wellington.

Mushrooms can taste "earthy", and many of the best cheeses are technically "moldy" do you normally like mushrooms? I would guess it may be the flavor profile you don't care for, as I would doubt they would send out spoiled product, if that were the case the meat itself and pastry would be "off" tasting or furry.

I already did and they sent a new one.If this one taste the same I assume its supposed to taste that way.

Doesn't sound right. Contact their customer service department for a new one.
