Bad service

I own a fish and chips franchise store in Jane Furse and I am supposed to sell the red bull drinks in my store. I bought these drinks in April through Digistics and still waiting for a cooler to put these drinks in . I am not having any luck with Red Bull the area Rep Kamo doesn’t even answer my messages nor my calls since April. Not sure what to do with these drinks . They service is so different from Coke . Cokes service is excellent . Really disappointed
