Bank card **** by city of Cape town

Hello Peter, I am so angry and disappointed with services with city of Cape town , kuilsriver. The machines I think are scanned. 3 months ago I went there to pay my rates R2k plus and swiped with my card. Declined but money went through and was never authorised with my bank. THe cashier and manger told me to come back the following day and check as the money was not showing in their account. Went there the following day and manger told me my money is not in their account and there is nothing they can do about it😳. She was very rude and I had to go-to Bellville municipality and paid again there with the same card and no problems. I informed them what happened at Kuilsriver, they took my documents and details and sent an email through to kuilsriver and on my way back I recieved a call from the same rude manger telling me she recieved an email and my money will be reversed in few day. I asked her where tthe money was coming from as it was still unauthorised by my bank, she didn't reply on that and in 2 day my money was in and was not showing on the bank statement shocking. She Called me to confirm if money was in and I said yes bcoz she wanted to close the case. Now June 19 went to pay for my car licence disc R750, same thing appended😡, I paid cash again and the supervisor said they will reverse till today have not recieved my money. I called the *****line and they took my details and said they will call back and investigate, no call till today😡. I want my money back our cards are scanned there and not doing anything about it. I might not be the only victim. I'm very angry right now Pls help😡
