Disgusted with Absa bank!

So on the 22 July 2018 I by accident deposited an amount of R1050 into a flash mobile account. An account number was used which is my cellphone number. I then went into Absa branch Linton Grange Cape road Port Elizabeth and they then contacted the Flash mobile agent. Her name is Cynthia Diba, she then told me not to worry as i am not a flash mobile account holder and that the money was deposited to my cellphone number, no one else has access to the money and assured me that i should get it back. She then told me toWhatsApp my details ( copy of ATM slip, bank statement) through to ********** 008 and after sending through all documents I should call the Flash centre on ********** 274 or ********** 274. I have done so and they told me they have received my documents and they have sent it through to the finance department for approval. On the 24th July 2018 I went into Absa again as I did not get back any feedback and the customer service consultant then contacted flash mobile only to get told to send my documents to the given WhatsApp number above again. I did do that and Cynthia told me she was going to call me back. She then called me back to confirm my account number and told me that finance department has approved to do a reversal. The following day Cynthia called me again confirmed my account number and told me I should receive a SMS shortly to say that money has been deposited into my account. Today its 31st July 2018 and still no money has been paid in. I have waisted R300 Rand on airtime as well as petrol money up and down to Absa branch. Its really disgusting to get such pathetic service from Absa bank as I have been a client of them for over 9years now. And have decided to close all accounts with Absa as well as to cancel all policies taken out through Absa.
