Thank you very much for your support!
We've checked to see your last payment was on Feb 14, 2017, and you paid 1 year. Since there was a promotion then, so you've been offered extra 6 months for free. So the expiration date for your account is on Aug 13. 2018.
If I've made any mistake, please don't hesitate to tell me and provide me the screenshot of your payment info.
Have a nice day!
