Vodacom is the WORST!

I completed my two year contract and decided to cancel, but I have been struggling for a year to cancel. I went to the store...the referred me to the retentions department. I called the number and waited more that 30min on the line before getting to a consultant. There systems were off line, but she promised she would cancel it, but never did. I called back after a few months, realizing that I am still paying for the contract and for a full week week I could not get through. When I eventually got through I insisted on speaking to a supervisor who also promised me that she will cancel it...she never did and I am still paying monthly. I went back to a store, trying to cancel...they acknowledged that my contract came up for renewal a long time ago and I could cancel, but they can't help me, as I need to call the retention line. I CAN'T GET THROUGH THAT LINE WITHOUT WAITING FOR 30 min. It is now a year later and I am still paying month by month. THIS IS RIDICULOUS. WHY DO THEY MAKE IT IMPOSSIBLE TO CANCEL A CONTRACT?

I have rated them 1-star, but they actually deserves none.
