VODACOM - No service satisfaction

After numerous failed attempts to cancel two expired contracts telephonically on *** , I emailed Vodacom at *** explaining that I get no response from phone calls. Their response from a different division, ***?

" Please contact the Cancellation Department 0n *** to request cancellation ....you will receive a SMS prompting you to rate my service. We'd love to hear your feedback"

Well here is my feedback. You gave me NO service, so I cannot rate you very high. I still have two expired contracts that I NO LONGER want, and I am still trying to cancel them. Any other ideas on how I could contact you to cancel them!!!!! A human response to my actual query would be greatly appreciated
