Vodacom #noservicedelivery

My experience with Vodacom has been hell on earth. Many billing issues previously which almost lead me to change service providers. Now when you ask to speak to a supervisor or manager you get put on hold for who knows how long and then your call gets dropped. Do I not deserve to get great service from my cellular service provider anymore? And my call being dropped on 2 occassions. Once again I redialled their accounts department I left my number for them to contact me nada no response. Is this a slap in the face after you have received all my loyalty for many years? Thanks for the not so good service Vodacom
