Cell C wants new customers but treat the old BAD

I called into the Call Centre on 20.07.2015 @ 11h45, to be met with a rude, insinuating Cell C employee (Marvin or Melvin from the Durban Call Centre). He asked me for a reference number, upon which I said that I was not previously given one. His reply was that that was IMPOSSIBLE, but he would check. I explained that by him saying it was impossible, imp**** that I was lying and that there was probably a reference number generated but it was not given to me. His retort to that was \WHATEVER!!!!". I lost my patience and said to him \""Don't you F%$&en say Whatever to me\"". This is when he put the phone down in my ear. I called back and was met with Lerato Moloi (Jhb Call Center) and she referred the matter to her Supervisor. She said that her Supervisor was listening the recording. I needed to urgently leave at the time and asked Lerato for a reference number"
