Sheild911 unfare practice : they took extrs money by debit order that they don't want to refund

I Kobus Pienaar joined Sheild911 July 2019, there was a double debit order gone through so I phoned them and they refunded me, August and September double debit orders went through again I made 5 phone calls to them and explained everything to them even spoke to a manager 11th October and she said someone will contact me before 12 on Monday nothing happen I phone again on Tuesday 5 November spoke to a manager a lady called Patty and she promised to take it up with the CEO and till to date nothing Every extra debit order cost me extra fees as well as all the phone calls According to my situation they are ***** took extra money R240 that they don't wanna refund, I'm very unhappy with Sheild911
