Cancellation

I do not even know where to start because at Vodacom they now have machines speaking to you instead of calling you directly, I enquired for a cancelation quote on the 1st June20 my contract that is ending dec 2015. 1.I did not have a phone at all that time and did not qualify for a pre mature upgrade. Well got the quote that says if it not sgned and returned back within 7 days it is void. I did not sign nor pay for the quote, on the 25th of June I went and visited the Irene Vodacom shop and to my suprise on Morpheus my number had been converted to prepaid already. 2-but when I call retentions the consultants say it is the Shop that converted the number. My Question is since when does Vodacom process any servise without paper work??? Now it cannot be reversed in order for me to carry on paying for my line till dec when it ends. I fail to understand the stupid people hired there, And the consultant Duan said he will return my calls as he sent a service request to trade partners. I am very annoyed because I have seen this happening when I was working there and I treated all customers as important but the service I got?? will not be paying for any extra charges on my account Vodacom.
