Lying about billing

This is a follow up on my previous complaint about bad service....cutting of my bis without notice, before my contract expires. Then they rep**** with a sms saying the following ( copied)... Dear Rolande<br> <br> Please be advised that your BBM service is still active on your number and profile. The new package for the upgrade will only take effect on 28-02-2015. <br> Kind regards, Vodacom Customer Care Shameegh Frieslaar.....but now you bill me for this service? Is this just incompetance or stupidity....or would you like to blame you system? Acc no I***-0
