Incorrect Billing

I paid my monthly premium of R150-00 to Clientele Legal on the 28th September 2015 via EFT as I could not change my banking details with Clientele in time (as I received delayed responses and poor service - I have e-mails to prove this). I contacted Clientele on the 18th September to assist in changing banking details. Sizakele Masilela called me (the phone rang twice) and then sent me an e-mail saying he couldn't reach me. I once again complained immediately and was contacted four days later when it was now too late to immediately change banking details for the debit orders were run. Thulani Mazibuko e-mailed me on the 25th (actual debit order date) informing me that my banking details were changed but would only be activated from the following month. I then made an EFT payment and I also received an sms from Clientele thanking me for my payment. I then see that Clientele have now gone and run the debit order off anyway (on my old account) even though I have paid already. I have therefore been billed a dishonesty fee from my bank. This is pathetic service. I would like a refund for this dishonesty fee. Please contact me.
