Horrible service

I have never experienced a horrible service in my life like the one I recieved from Menzi Ncube from Supersonic. I was transferred to him (acc depart) so he can look up for my details on the system as customer service could not find me on their system, by the time I was transferred to him I had already spent 15 minutes on the line, he also kept me on hold for +/-30 minutes searching for my details, when he got them he was telling me 'who my name is' and just transferred me without giving my details to the customer service agents that didnt initially have my details. I had to repeat the same process twice and ended up speaking to 4 agents all in all with my airtime, Menzi Ncube was rude and didnt speak to me in a manner that made me feel like a valuable customer which is why I am even contemplating in changing my service provider.
