Think twice before buying from Qubist

My son bought Sony Headphones and Qubist delivered on Saturday afternoon. After testing them that evening he found the sound quality of the microphone to be very poor. On Monday morning we returned the item to Qubist and they refused to give us a refund on the goods and told us to contact their Supplier. I contacted them Tuesday afternoon they were abrupt and seriously rude and said that they would not give us a full refund on the items but would charge a 20% handling fee for the box being opened (a re-sealable sticker). I told him I was very disappointed and his answer was \Well that is your problem\". I will never buy anything from Qubist ever again. If this is the way they do business then I will choose to go somewhere else. We have taken similar things to reputable companies in the past and have never had this kind of service. They really simply don't care about their customer.
