Cell C are *****ing from his customers

Good day. I have paid the cancellation fees for 2 contracts in January and I get billed for it every month after that. I just received my March invoice, and can you believe they have billed me for the two contracts again. I don't know who to speak to anymore. I really can't afford this to keep happening. I am so frustrated and angry. Wish I could get rid of all my contracts with Cell C as soon as possible. Please think carefully before you take out a contract with Cell C. They ***** our money and roll over and play dead. Very dissapointed customer.
