Instruct: Classify Amazon reviews into positive or negative sentiment
Query: Black mailed for a refund even thought the products were defective!!

Amazon really should have an option for zero or negative stars. I ordered 5 headsets from this company. NONE of them worked!! I emailed the company requesting a refund and was told the problem was likely with my phone. I tried every handset in 4 different phones and STILL none of them worked. I again requested a refund. The company request I return the items. I agreed to return them provided they supplied me with a prepaid return label. They ignored my request. By this time I had written a negative review here on the message boards. Shortly there after, I was contacted by an employee indicating they would give me a refund without requiring me to return the products but only if I removed my negative feedback. Their customer service is nonexistent and I am pretty sure their products are counterfeit!!!! DO NOT BUY FROM THIS COMPANY.
