Sudden suspension. No support to restore service.

Very poor service. Suspended my cell phone without reason or warning. Phoned call centre at 082 111. Call centre just keeps offering self service options, none of which mentions how I can restore my cell phone service, afterwards it hangs up on me. No actual person ever tried to answer my call. Tried to email support. Receives an automated email wanting details of my number (e.g. last recharge) as security check. Supp**** such details. No further email received from Vodacom. After much effort, I think I have to give up that number and I would caution any one trying to sign up for Vodacom that they may face sudden suspension of their service.
