See this reply by priceoye. 3rd of may is for purchasing date. For activation date is 19th may

I haven't receive my voucher. I called priceoye and they said they will resolve this soon. But 3rd may is for order date. For activation 19th may is last date

How long after activating your device the voucher appeared on your Samsung Members app

You are eligible as the valid date for activation is 19th may . I also activated my device on 6th may. I contacted Samsung and priceoye bothThey are working on it but based on the previous posts. I think it takes 5-6 days for vouchers to appear.

Did you call priceoye or samsung support
