If we sell it, we support it, regardless of which of our stores or certified resellers sold it. Send us an email or ticket, or call the support number for your region, and we'll assist you to the best of our ability.
If we don't sell it, we don't support it, even if it's an old ABU brand. You'll have to contact the store from which you bought the product.
If you're unsure, feel free to contact us. If it's not a product we support, we'll help you find the right place to go.
