Terrible customer service and over three months with no resolution - Help

Hi, How do I reach someone within Dyson service who can actually help?   I received a Dyson Airwrap for Christmas that began shorting out after 7 weeks of use.  I have been dealing with customer service for over three months - every excuse and ridiculous answer under the sun.   I have been told I would need to drive over two hours to a repair shop, when I replied saying that was not acceptable - the airwrap was purchased directly from Dyson, no store return option, I asked for a manager as was told one would caIl me back by then end of business day - surprise no call.   I’ve been told the model was out of stock and I would be contacted when available and one would be sent ot me - surprise no call in over FOUR WEEKS!!   With my latest call two weeks ago, I was given a runaround and finally told to mail mine back and should recieve a replacement within a month.   I was so frustrated that I asked to speak with a manager.  I do not want to receive a refurbished item and would like a manger’s confirmation prior to going forward as I have received so many run arounds and “shady” replies.   I was put on hold, told they weren’t available, the CS agent started to process the return label for service.  I told him no - I wished to speak with his manager and receive assurance/confirmation this is the correct process.  Again put on hold, told manager not avaiilable and used sneaky wording to again start a service return. I again declined and asked for a manger, again put on hold and then told i would receive a call within an hour but let’s start the service return.  This is all such a game and I was forcefully clear that a service was not to be scheduled and I’d be availble for the manager’s call.   He tried again to begin the process - I declined - he ended the call and guess what - two weeks later I still have no return call.   Vent/rant/ask for next steps over .    Thanks in advance.
