Missed Debit order

Iam very much angry at the fact that I called the call centre to change my banking details due to that there was ***** activities done on my Capitec. I spoke to an agent Zofa Gordon and was told that the banking details will be changed and the money will be deducted from my new FNB account. But to my shock i get a call yesterday from an agent telling me that the money was not received. I requested her to confirm which bank they deducted the money from and she told me that they took the money from my FNB account on the 25th February and there was not funds on the account, i told her that it was not possible because I had money in my FNB account. She told me to check my FNB statement because the payment was reversed. Then i did check it but there was not debit order send to my FNB account. I called the call centre again around 4:10 yesterday then I am told that the debit order was send to my Capitec account. I am not sure if you do not train you consultants on how the system works. In the first place I took my time to call the company and inform them on my new account number and was told that the money will be deducted from the new account. I find your consultants ***********.
