Banks

Yesterday I received a message from unknown resources. Your Egoli Rewards 135.00 debit will bill on 31 Jan as sold to you by Dialler Comm Ref TBDIALC*myID no*190131. Reply CANCEL to stop or call ********** 239 Which I did not join anything like that and as in like now they debited my account R135. My question is where does this people get our details as it shows that they know more about us as they can link my ID with my account. I want the bank to reverse my money as it is
