After one year, my Dyson v11 Turbo stopped working. I called support and it seems the motor on my unit failed. There were no replacement units in stock but I was advised that they would get an upgraded unit shipped out.
Two weeks later after not receiving the replacement unit, I called back. I gave them the serial number and they asked my address to confirm it. After giving them my address, they advised that that was not the address on file. I went back and forth and waited on hold for 30 minutes while they checked with security. When thy got back on the line they gave me the address they had on file and sure enough the last person I spoke with duplicated the street name with the city name, then they advised that they had not received my defective unit back. What? No one asked me to ship it back! They said I needed to ship my defective unit back (EVEN THOUGH IT IS STILL UNDER WARRANTY) and in a few weeks after receiving it, they would send me a replacement.
I took it back to COSTCO where I bought it and they gave me an brand new exact replacement.
DYSON CUSTOMER SERVICE IS A WASTE OF TIME!! The WORSE I have EVER experienced. What a shame. There is NO excuse for it!
