1.Notification received Irrelevant, 2.features offer 512 blocks not showing full details.

Hello good day mam sir
Where I should I ask about coupons I just recently bought 512 blocks for LIFETIME membership but I didn’t even know it has expiration until nov, 6 2020 I think did I misunderstand something. Any assistance pls.?
And also the notification we receive is NOT specific about it just indicate reply how I can simply managed all the replies if some of them are not mine..! When I clicked the notification it directed from there but not overall mentioned me it just replied to the other account how annoying 
What is the full definition of that features exchange blocks 90,000 into satoshi? How is expiration log limit expire I mean how many hours is that based on country to country or based on international time like GMT? 
I have overall 3 questions sorry for that I wish you could answer all of it thanks!
