Vodacom

On behalf of my mother. She is 77 years old. A year back Vodacom phoned her for new phone (her English not good). If she said yes or no I cannot say. She received a phone and she send it back. She used her old phone , and she get billed for Smart Top up S on her number ( she have this for years ***) She is complaining about her cell phone account and asked in the store for a billing statement . She found out (I know only now) that she is paying for a phone she don't have and airtime she never used for more than a year. There is no activity on that account - which means that this phone is not in use. This is the no of the phone she returned - *** the number she got billed on. She went into a branch in Bloemfontein for help. No one is able to help her. I try to phone and help her but they are not able to help me because I am not the account holder.
