Arrogant call center agent should do his work before insulting customers

I had a geyser claim and dealt with a call center agent called devon pillay-riches, and wow what a BAD experience, this is the WORST claims experience I HAVE EVER HAD, the arrangements made to replace the geyser was not conveyed correctly to the sub contractor and resulted in the ceiling will only be repaired days after the geyser replacement. But the major issue I have is with the call center agent who would not listen to the client and when I asked to speak to someone superior his comment was "CAN YOU KEEP QUITE SO THAT I CAN TALK" this is after I told him on two occasions to put em through to a supervisor, after he insulted me by saying I was vulgar to him which I was never by the way, and that normally when a person was vulgar to him he would put the phone down as this was the company policy (WHAT!!!!!!). Thank you to Noni Mathe for getting the solution resolved, but it didn't make up for the nonsense I had to face from that call center agent.
