Vodasure - the looting continues

I posted previously to say that I am still getting charged over R200 per month for Vodasure cover on a phone I don't even use any more. Vodacom made one attempt to contact me (a missed call with no message left) and then responded on Hello Peter falsely claiming to have followed up by email. Surprise, surprise, I have just been debited again! I am now in the UK and seldom use my SA number (on another old handset), so I would really appreciate a prompt (and honest) resolution. I want the Vodasure cover cancelled with immediate effect, nice though it may be for Vodacom to have this passive income stream. Please contact me by email on ***
