Nice to see you here in the Community, @Steve2702. We'll be glad to help you with your gift voucher to get the discount on your QuickBooks account.
After the first 120 days from the start of the subscription, we aim to deliver the voucher.
If you have not received the voucher in that timescale, feel free to come back to this thread and we'll be able to make sure that it is sent to you.
In addition, here are some articles to keep you safe from potential fraud activities: Identify suspicious activity, phishing scams, and potential fraud.
Please post here again if you have other concerns with QuickBooks that you need help with. I'll be right here to help you out. Have a good one!
