Coffee Percolator

I bought a coffee percolator for $93 on internet and received it, but the percolator was not working. I communicate with them and they told me to sent it back for a refund. The shipping cost from South Africa was very expensive R$117 and I told them. However the agent said they will refund me in full as soon as they received the parcel. They did refund me $93 for the percolator and only $25 for the shipping costs. The only way to contact them is via a review (3 times) that I did, but they never came back to me. So I paid $93 for absolute nothing and very poor after sale service. There is no way to contact Amazon.com by email to discuss this matter. It is a shame. Leon Brits ********** + ********** 9119
