Achieving service excellence - non-existent!!!

My first call to vodacom was on 17 July regarding the cancellation of my contract. Retentions then \offered"me a package which I requested them to send via email to *** till today I'm still waiting for this email. I 've logged 3 complaints on their website already and receiving responses that a \""senior consultant\"" will give me feedback - no no avail...no feedack received as usual. Pity I need to run full term contract until early September - would have loved to change service provider 2 months back.... Eisch!!"""
