Due to company policy of discontinuing the use of Expensify as reimbursement tool as of November 2018, I had to stop the subscription after 1-year period ended by Jan 2019. However my account was charged 10us$ on February 1st 2019 even though I had disabled the auto renwal option on my account settings November 2018. Did anyone can tell me how this happened and what to do to get this 10us$ back to my company credit card? Thanks !
