MTN not reachable at all

On behalf of my mother, she has an account with MTN for 3 lines and for over a year she gets told by MTN's customer care that they cannot assist her, she needs to contact Cathy Botha, her Account Manager. She has emailed, faxed, called on her direct cellphone and NO ANSWER. On one of the other numbers there is an insurance claim, which was NEVER submitted, the insurance is not reachable. The handset is broken and needs to be fixed urgently!!<br> <br> Hours are spent trying to call MTN - but she cannot get through to them, nor this Cathy Botha, her Account Manager. My mother does not even receive her statements, after asking monthly for this!!!!<br> <br> Please can someone assist her with her MTN lines!!!!!<br> <br>
