Zero stars, absolutely appalling service

I took my Dyson airwrap into the Bryanston branch 3 weeks ago for repairs as it is still under warranty. I was told I would receive email confirmation that it has been booked. To date I have received nothing. Zero communication. I phoned the first time and was told they would ask the technician to get back to me. Nothing. I phoned again, got through to the CT branch as apparently the JHB phone lines were down. A message was taken and I was told I would be called. Nothing. I phoned last week, was then put on hold, when the call was transferred back to Melanie she said ‘Oh it’s you, I thought you had dropped off’. She tried to transfer me and the phone just rang for minutes without answer. I am honestly speechless that a brand like Dyson has this level of service. I would love to share my ‘booking reference’ but I have nothing. Never in my life have I experienced such horrific service (actually to date I have had no service). But my personal items are now just at the mercy of this ridiculous place.
