Your post was blank @joshnaj1746 and you'll need to provide a bit more information if you want assistance from the Community Forum.
How exactly are you trying to buy a membership plan?
On the app? On the website? Does it make any difference if you switch between them?
What happens/goes wrong?
Any error messages?
When were you last able to buy a membership plan?
Are your payment card details still valid?
