Who is the idiot now?

Me being emailed an itemized bill and deregistering has not fixed any of my problems. My ID number is linked to another account. Could Vodacom kindly refrain from doing the same thing over and over again. It does not remedy the problem. I cannot say what a problem is and how it was not fixed the previous times and yet Vodacom will proceed and do the same thing. Deregistering my cell number does not assist in any manner what so ever!!!
