how long am i blocked on instagram?

[Olivia]

my sister and i got into a fight i was stupid and left my phone unlocked on instagram. My sister took my phone and searched weird hashtags that i never use like "like4like" and "FollowMe". She went down the hashtag feed and liked over 500 pics, scrolling really fast. I didn't notice until weird people wanted to follow me and when i tried to like one of my friend's pics, instagram said, "You're Temporarily blocked. It looks like you were misusing this feature by going to fast. You've been temporarily blocked from using it (liking pics). We restrict certain content and actions to protect our community. Tell us if you think we made a mistake" i clicked the tell us button and they sent me to a page describing why they shouldn't block me. I typed in how i'm very sorry and explained how my sister took my phone and promised that she would never do it again. Has anybody experienced this problem before, and if so how long before they fix it and i can start liking pic (reasonably) again. Also if they have a customer service number that is legit that would also be helpful.
Thanks and sorry for the long question.
