Cancellation of poor service

Ref: ********** 123. Good day Cell C. First off I have now canceled all my contract with you as the result of your poor service . I have complained to you about why my billing is so high every time and for the last 2 weeks you have been just wasted my time by not supporting me on my problem but rather to send me to every department you have at your company. Please get my account sorted. Then on Saturday you accounts department informed me I am paying for a different contract than wat I am receiving and rever me back to your technical department.
