I contacted Dyson via Whatsapp on Nov 25th with regards to Black Friday Promotions, and was informed of a 90 days money back guarantee. I gave it to my wife on her birthday on Jan 30th, but unfortunately she didn’t get on with it. Today when I contacted Dyson for a refund, I was told that the 90 days period has expired, when it clearly has not (it has been 81 days since Nov 25th). I’m struggling to understand how Dyson is calculating the number of days since purchase (how is it 90 days from Nov 25 to Jan 25)?
