*****ulent charges while sleeping

my wife used Uber yesterday to and from home access park in Cape Town, the sms's went off the account, Great done deal. while i was sleeping @ 3 in the morning a charge goes off again on my account for the same amount of both trips, as i am working out of town and i had to phone my wife awake at that time to ask what is going on. she checked her email and yes there is is the trip that was booked from access park to home. so please guys check this cause im not letting it stand there, we work hard for our money to get ****** while sleeping.
