Having problems with Payment Gateway

Presale question:

i have a membership website for food (woocommerce membership plugin), i study the plugin free version and im good to have code to .php etc…

what i need this plugin to do for me (if he do):

if regular or no member can’t buy anything.
if gold member can buy only 70 product per month (stop if membership do not renew, but can buy the rest of quantity and or get the rest of the quantity for the next month)
if silver member can buy only 60 product per month (stop if membership do not renew, but can buy the rest of quantity and or get the rest of the quantity for the next month)
if bronze member can buy only 45 product per month (stop if membership do not renew, but can buy the rest of quantity and or get the rest of the quantity for the next month)

now its for all product category gold and let said if you buy as a gold member
5 product A
2 product B
you have 63 product to buy left this month
but if you try to buy 70 you can’t.

for the free version the product do not update in the page of Product limits or the page product itself so you cant buy as much as you can no restriction (bug?) i know its a lot and i’m sorry.

thank you.
