Instruct: Classify Amazon reviews into positive or negative sentiment
Query: Too complicated

When calling to engage the warranty, there is no uniformity of service:1. Once, I had to call 4 times to get someone to help--the first 3 times, I was told, "We'll get back to you."2. Once, instead of allowing me to take the product to a local dealer, they made me ship the product to a repair service at my expense--box and mailing were almost $40.3. Once, I had to argue that I knew the repair could be done locally--had to speak with 3 representatives before the company agreed with me.4. Beware of Dyson's rehab vacuumes. Yes, I am grateful I have an extended warranty but the quality of service stinks
