Again Checkers wont Deliver

We have been using checkers food services for a couple of months. We order allot of milk from them. The Checkers house brand long life milk. Every time we stocked this milk we had some sort of a problem. Some of the boxes are either invested with maggots or rodents have nested in them. We store our milk in a locked safe so no contamination from our side. Now I have asked their regional Manager JA Geldenhuys to please come up with solutions but as always he never believes in customer service. We did not ask to replace any of the spoiled items just to come up with a solution to prevent this from happening and contaminating our work place. Very Very **** bad produce and service from checkers.... as always.
