Complaint ignored

I had cancelled my Vodacom contract and was told that it would be switch over to pre-paid on the 31st of July. <br> Out of nowhere, and with no warning at all, my account was switch at 8.26am on the 22nd of July. I was left stranded in the middle of town with no way to phone work and no GPS. <br> When I phoned to complain, I was passed from one person at customer care to the next, with no satisfactory answer as to why my phone had been switched 9 days early. <br> Eventually someone from their online help desk called me and she checked the system - it was scheduled to only switch on the 31st. She said she would escalate the complaint. It has now been 19 days and all I have received is an SMS saying it had been referred to IT. <br> No response, no acknowledgement of the complaint.
