Vodacom poor service

I have been struggling since yesterday to get my fathers service reconnected. Last night I spent 50 minutes trying to sort it out and by the time somebody tried to help their account department was closed and i could not be helped. I give the young lady her due - she promised to arrange a call back this morning and a gentleman did contact me. However that is the last time I have had any service or contact from Vodacom. I have left 3 call back messages which are still unanswered! My father is 84 with a heart problem and cannot be without a phone.I need someone to please URGENTLY contact me to sort this out!!.
