Asana Rebel Renewed My Subscription Without Approval and Increased the Price

I most certainly did not approve a renewal and hardly utilized Asana Rebel more than a few times. Still, they charged me automatically, at an incredibly ludicrous level! It was $35.99 last year; today they took $174.99? That exceeds a four times increase! In only one year, how does a membership jump so much? This resembles only abuse. And I'm not the only one; I have heard countless complaints on this dubious price. Their continued escape with it irritates me. I want a thorough explanation for this ridiculous fee and a complete refund. How can they defend this sort of price increase? If you are considering registering, be cautious; they will trap you in a costly renewal before you even realize!
