Sasol garage N12 very rude and unhelpful management!!!

Good day, I'm very dissapointed with the service I received at sasol garage, the one on the N12. I went there to pour petrol of R250 and after the guy poured petrol he brought the speed point and tapped my bank card then his machine died. I got an sms notification that money has been deducted from my account then the petrol attendant was scared that what if the money reverses cause machine died then called his manager, he asked me to swipe again and assured me that my 1st 250 will reverse after I swipe for the second time. I swiped for the second time and got another sms notification and even checked on app that it was two payments and the 1st 250 didnt reverse and he asked me to call the bank to reverse it, I was irritated cause he assured me it would reverse and now his making me call the bank. We called the bank and the bank confirmed that it was two transactions and the manager refused and says when he re prints its 1 payment and was so rude to me, I think his name was Ali. Very rude and unhelpful and told me that there was nothing he can do and that I must reverse that amount cause he can't help me.
