SAB-unable to resolve the error they made Aug 2015

I urgently need someone for SAB who can assist me. I am a big SAB customer and sometimes last year in August SAB billed me incorrectly, for the order (stock) that was never delivered to me. I logged a query with Craig from the depot, Richard and Toni are also aware of the matter. My biggest problem is that, I am currently unable to get more stock delivered to me because my account is said to be blocked because of this matter, even though the fault is from SAB itself. Could someone please contact me to give me an explanation of why is it taking so long for the Breweries to resolve the error that they have made?<br> <br>
