I bought Dyson V11 from david jones online, in april 2020 and it stopped working within 3 months of time, i called David jones to provide replacement or exchange and the staff was so rude he said its dyson so we have nothing to do with it and said its my fault that i bought it online so no sales person was able to tell me that if any issues david jones will do nothing in case of dyson products....I called dyson and they said that i should contact david jones for refund as i didnt buy from them, I cannot believe thats the level of service from such big brands its been 2 months me calling these both places with still no vaccum
