Poor Client Service experienced at Vodacom.

Good day. Today I called the Cancellations department of Vodacom to terminate my contract when a young man answers the phone. I ask him to terminate my existing, when he starts selling me packages. He was so focused on selling me a new contract that i had to ask him thrice to terminate my contract. The call is then cut and I call again, this time I hear him cough and the line goes silent again. I then called via the Call Centre and am transferred to the Cancellations department and request to be transferred to the supervisor when I'm questioned by the same man, "why do you want to speak to my supervisor" and the line goes silent. I tried calling several times even from a land line and when you asked for the cell number concerned, you are asked to call back later. You know what is disturbing is that its gonna happen to others as I have addressed this incident with senior managers and received an apology but that's it. No talk of an internal investigation. So for being a valid client for all the years means nothing today to a large international company as Vodacom. Be warned of the declining client service.
