I have a new hot + cool jet focus fan.  Tried to register it on the website.  It will not accept the serial number.  I have checked the number and tried several times.  Then tried to do it by telephone, as instructed, but there is no option to register.  It is really a bad experience so far.   Then tried to use the chat - eventually said they will get back within 30 Minutes.  The pre-selectedoptions do not include an inability to register the product.  Anyone know why Dyson is so difficult to deal with and what I can do?  Thankyou
