Automobile Association bad service

On the 5th of June 2018 I phoned the AA offices at Centurion Lifestyle Centre to buy 3rd party insurance to go to Mozambique. The lady assured me that I can come in and buy the insurance. When I arrived I was told that they were offline for some time and do not know when they will be back online again. I went back the next day and it took an hour because the lady was battling with their new system. On the end my credit card was swipe and I received an SMS on my phone. The next morning the lady phoned and told me I must come in again because my payment did not go through. I checked my credit card account and it was pending. Phoned my bank and they said it would go through. Phoned the AA and she kept insisting that I must come and swipe my card again. I told her to cancel the transaction. I went onto DriveMoz bought it for cheaper in less than 15 minutes. In the meantime the transaction went through my credit card. I phoned the AA ********** 234 were transferred 3 times and then got a recorded messages that they can't help me at the moment and that I must try later. I phoned the Centurion branch and was told they cannot reverse the transaction. Any suggestions?
