Granting online purchases without my knowledge

On May 10 there was a ********** online purchase from wps on my account for R815.21 . when I phoned the bank to inform them they cancelled my card and asked me to send relevant information that I didn't sign up for any subscriptions. I contacted google play as I was able to track that this wps company was a google play app. There was no subscriptions on my name and yet Tymebank didn't reverse my money as there were no evidence that I subscribed for something that I have no need for. Please assist in getting my money back as I need it more than a company called wps that was granted access to my account without my knowledge. I have been with Absa for 13 years now and never did they let an online purchase be processed with the person putting their details online for a online purchase.
