STILL NO ASSISTANCE AFTER 2 MONTHS

I wrote a Hellopeter complaint on 10 March 2015 about a transaction for R1 085.68 that I don't know about & that Nedbank authorized to go through despite my credit available being only half of that amount. I was then told to fax a dispute form which I did so on 11 March 2015. After that nobody bothered to come bank to me until I wrote yet another complaint on 21 April 2015 to which I've been told they are attending to the matter as usual. 16 days later still no help & to top it all they have the nerve to follow up on payment knowing very well they still have not helped me one bit. This is PATHETIC!!!
