Over a month and still no refund from AA

I am exceptionally frustrated with the lack of action from the AA - they have owed me money for well over a month now. On 11 February 2019 I paid R2 090 to the AA for AA Advantage+ membership. On 15 February 2019 R1 200 was deducted from my bank account by debit order for AA Advantage (my previous membership). I understand that the time difference between my payment and the debit order run was very short to stop the debit order so I contacted the AA by phone on 18 February to explain the situation and ask for the R1 200 to be refunded to me. I was assured that the request would be passed on to the Finance department and that it would be done. After two weeks I had not received a refund nor had I had confirmation of my AA Advantage+ membership. I then filled in the contact form on *** to explain the problem. On 11 March 2019 I received a phone call from an AA consultant who assured me that the matter was being dealt with and that I would receive the refund of R1 200 by Friday (15 March). I have still not received the refund. On 18 March 2019 I filled in the contact form on the AA website again, emailed the AA and sent them a direct message via Facebook. The only response I received was to the Facebook message saying someone would contact me. The next day I received another message on Facebook asking if I had been contacted - I had not heard anything. This morning (25 March) I phoned the AA and spoke to a consultant who informed me that the matter had been escalated and their finance department would contact me within about five minutes - that did not happen and now, one hour and twenty minutes later, I have still not had a call. After three empty promises and many no responses I am completely frustrated and very disappointed in what used to be an organisation with a good reputation - I have been a member for approximately thirty years and this is just not good enough!
