Very versatile unhappy client

So I had 3 payment deducted from my account without my knowledge and consent .I then contracted Capitec Bank ***** section which transferred me to customer service . No help. I requested to stop the pending payments and I have stopped my cards as well. I was told.on so many occasions that they can help or try and stop the pending paymens. I was then told to log a dispute with Mastercard. I was not offered assistance to do it on my behalf which is the client The sad part is and shown to me that Capotec Bamk had no policy in place to assist to stop this pending payment and myself the client need to contact the merchant who I have no idea that is . So I'm losing R1400 just like that and the bank just blantly says they can't help anyway to get my money back. So sad from a bank that has such good banking fees . I'm sure I'm not they only who have experience this . Sother banknatleast have something in place to stop these type of payment and when I payment goes off your card it should authorize by any isn't yet I was told digital payment do not get authorized by the bank and plainly put it . It's the client responsibility and fault
