CEO to important to respond to customer complaints

Upon recommendation form insurance company fitted 4 devices 3 months ago, one worked for a while the other 3 did not, still don't, went back to fitment centre, they tried to help no success. Took over to try and sort out with HO, but CEO is to important to take calls from CUSTOMERS, the gatekeeper puts you through to \customer service"what a bunch of ___. \""Customer service\"" phoned a few times but did not sort out the problem"
