Bad service from Manager

I went to fuel up at Caltex Spin road in Litha Park Khayelitsha. After punching in my pin using my card the petrol attendant let me know he was confused as it usually states approved and it didn't it just went off, he asked me to check if I had received and sms I checked and indeed the funds had gone off. He went to enquire inside with the cashier he came back saying it would reverse I should wait, it didn't reverse and I was impatient as I had to go somewhere he then told me I should swip again maybe it is because of network that is why the funds haven't reversed back into my account. I told him that will never happen I will never double pay and at this point I was getting impatient he was inconveniencing me and I had to fetch my kids from school. Their dad insisted he would speak to the cashier and they should go together as he could see the petrol attendant was panicking and I was getting annoyed. They came to an agreement that he should leave his driver's license and come back Sunday if the funds do Infact reverse he would then swipe again. We left and returned Sunday only to find the manager there a d the cashier was off. He told us to just pay back the money as the card had declined, he said that he had dealt with people like us so many times and we should just pay back the money he refused to listen to the explanation of what happened his mind was already made up, he was extremely rude and demeaning we decided to wait for the petrol attendant as we thought maybe he would explain to his manager, what shocked us is that the petrol attendant changed on us too he said our card had declined and that we should pay back their money it was shocking as this was not what he said Friday, his speedpoint machine had a problem it was like he was scared of that manager and he was just saying what he the manager was saying. The manager even called the police saying we will not get the drivers license we should just pay the money. I resorted to saying I will not speak to him as his problem solving s****s are lacking he was not listening to us at all. I demanded to speak to his superior he gave me the run around there too saying he was the manager, I told him I wanted to speak to the person he reported too. He called a lady called Mrs Ebrahim, she agreed to meet up with me and I should bring the card and they will check on the system what was going on with the payment, that was all I wanted for them to chqck before making a conclusion as I had already contacted my bank and they said the funds had left my side waiting on approval from Caltex. Monday I got a call from the cashier that had assisted us initially so she said I must come in and she would check for me. She took my card number and checked and indeed the funds had been received. All that drama for NOTHING, had the manager listed and checked before concluding this could have been avoided. Still on Monday when I was being assisted by the cashier he did not apologize instead he was laughing at videos on his phone. He is rude and ***********, so is the petrol attendant that assisted us. I am extremely frustrated with that service and an apology from both of them would be great.
