Was not told of additional costs

I was told that goods would be couriered to my address. No one mentioned Post office delivery and fees. I now have three boxes to collect at R2000 each box. Thats R6000. The supplier is no longer responding to my emails. I run a business and these addional costs have killed my profit and now my prices are no longer competitive. I am disgusted at the fact that now no one is replying my emails. [Email Removed]
