Sold me a $417 product not suitable for the advertised task. After attempting to trouble-shoot I discovered on the product's forum this was a huge design flaw that many users had discovered. I contacted Computer Alliance 4 days post purchase and asked to return. over 15 back and forth emails with this store, often having to prompt for reply after many days of silence etc, the Australian Competition and Consumer Commission got me a full refund (minus delivery) within 1 day. I will NEVER shop here again, and I warn my friends of the stupid amount of energy and time that went into getting any assistance from this store who even has it in their store policy that under the exact circumstances of something being unable to perform the task it is sold for, it can be returned within 14 days of purchase. Where would we be without the ACCC
