They will blacklist me ???

You didn’t miss anything. The deadline to confirm your win for that giveaway was October 3rd. Now if you didn’t confirm it before then, then you just won’t get the product. They won’t “blacklist” you. but always check your email during the end of giveaway dates. The deadline to review the product isn’t till November. November 18th I believe (I won it as well). Please read your email in full, scroll all the way through it, it explains everything you need to know. If you do not get your products before the deadline (November 18th), then you fill out the form, that is also in the email, and you won’t be penalized and get an extended deadline so you can review the product.

maybe they will blacklist u bcs u dont confirm that the product havent arrived (u still have to confirm if u havent received the product on the gform)
