Cell C Sucks

After trying 2 months to cancel wifi contract i eventually succeeded just so that they keep debiting my account and now with more than R1100 after my contract was just R139 pm. When I phoned the call centre to find out what is happening, the person I spoke to, Kygo or Kego (something like that). He didnt even ask an account or cellphone number, he's fist answer to me was... It's because you owe us money, how does he even think I owe anything as he didn't even know he was speaking to? The more I tried to explain the story the more he told me to keep quiet and listen to what he is saying! He's customer service is up to #$%&! How is he even in a customer service position if he speaks to one as if he owns Cell C. I still tried to explain my situation when he decided he doesn't want to talk to me and dropped the phone in my ear! Needless to say I still don't have an answer to how to get a refund. It's extremely frustrating to deal with these type of people, people that have the job but no idea how to do it!
