MY SUBSCRIPTION CALCULATES IN A WRONG WAY

Yo, guys. So basically when I joined manychat in June. I was in a trial period and it ended at June 22nd but then pro version stopped working obviously and I wasn't using any of the features. I couldn't pay at that time cause I didn't have any money on me, now today at July 11th I finally renewed my subscription but it says that the next payment is on July 22nd. How come is that? Since I wasn't using the features of the pro version from June 22nd why does it go like this? The moderators of manychat please change the billing period to a month from now, otherwise it's not fair and I wouldn't wanna use manychat in the future.
