Vodacom cancellation department

For two months I’m struggling to contract cancelled with Vodacom. I few times I when into the stores. I have been calling in to the head office. I kept told that back office will call me. Last week Monday I when to Maponya mall Vodacome store where I called in again. I was told again in three days I will get feedback. I ask for recording of the calls. Again a manager was not available. Up till today I got no call or email. And now I got bail that I have to pay. Instead I get calls for upgrade. I have no had this over to my attorney.
