That's not all. I returned the DOA power supply via UPS Ground with tracking + Digital Signature Requirement and 4 days later I got a replay from this email address:
hiandy@shop4tech.com stating that they never received my package, which had my name all over it and I notified their RMA & shipping dept 1 day prior to shipping it out, and whoever is hiandy acknowledged that he/she would look out for it. I was about to explode but I kept my cool and showed them the proof that it was delivered and their Shipping Dept. signed for it. Then "hiandy" apologized and said it is there now, and said will process my refund ASAP. Well, it has been 6 days since "hiandy" said that and I have yet to see an update on my refund.
This company is a big scam, it's basically ran by kids whom havent got a clue on how to do business, nor do they have any principles at all. AVOID Shop4Tech.com!!!!!
