Vodacom. Discontinuance not being done

No success in cancelling my package at vodacom. Requested discontinuance begining Feb Have called at least 6x. Have written emails to addresses on their website. Acknowledge receipt thereof but still not discontinued Went to the branch in Clearwater. Waited for ages to be attended to only to be told they do not do discontinuances. Need to phone . I no longer want the package and have given more than enough time to have it discontinued. Disgusting service
