Cell C are a bunch of sharks

I had a contract through Cell C that expired on the 8th of November, so I went in as advised by a staff member at Cell C on the 8th of October to cancel the contract, so that I wouldn't be billed again for it. A month later, I get billed again for the contract even though the consultant specifically explained to me that if I want to avoid being billed again, I must cancel the contract by the 8th of October, which I did. I haven't had use of the contract since the 8th of November even though there is 100gb of data on the contract that they won't allow me to use since the contract has expired but I am still paying for it... Bunch of sharks...

As a company, your customer service agents and in-store staff should be more aware of company policies when advising customers.
