Has anyone had a problem with hackers through the rover app?

i received a request last week for Dog walking for 7 days through the app from a Sara T who wanted me to reply to her email address, i responded through the app and stated i do not contact outside of Rover, i did not get a response after that but her request still managed to show up on my app calendar as a U booking that is synched to my home computer and both are apple products...i was hacked , my Apple id and password changed , i spent 2 days with apple support to correct the chaos this caused me...final word from Apple...its the app , linked through Facebook....i contacted Rover last week shared all my info I was told as soon as they pulled up her account it looked suspicious she had contacted others . Rover then blocked her account, i did not communicate outside the rover app but i was still hacked...cost me time , unneeded stress , my Rover app would not let me delete her off my calendar , rover seemed confused and clueless about how this happened , it took a few hours for them to sort it out...took App off my phone as a result
