Cell C lies

I wanted to cancell my data contract 6 months ago, Cell C begged me to stay and gave me a month to month contract deal with the comment one month no catches. Should have known better. I wait for Debit Order to go through and then I call to cancel. And guess what? They tell me I owe them ANOTHER installment so I have to carry this another month with financial challenges. Another R100 thrown away on lies. Thanks Cell C you can always be counted on to not keep to your word. And you know what I can do? NOTHING just pay.
