King Price Insurance - My worst nightmare

I have reported the same problem on April 20, 2015 and King Price refunded me the money incurred on my bank account. On May 6, 2015 another magtape was submitted to my bank under reference ***0 for the amount of R8205.21, which incurred cost on my account for the amount of R252.31. I wrote an email to Magdaleen Grobler and Jonathan Robertson on May 7, 2015 bringing the matter to their attention.. Magdaleen Grobler promised to investigate and give me feedback. I did not receive any feedback from her up to date, but instead another magtape was submitted to my bank on May 12, 2015 under a different reference no - ***0 for the amount of R8205.21. This amount was subsequently paid by my bank and I had to request a reversal of the payment on May 13, 2015. A new cost of R138,00 was again incurred. I don't know what to do with King Price as this is costing me money and time due to their incompetence.
