Blatant and extreme incompetance of vodacom consulant, team leader and manageress. Disgusting service from a so called reputable business

I have been a loyal customer of Vodacom for years and have several contracts with Vodacom. I contacted A consultant from cancellations department on Friday the 29th November who had made several promises to me which she did not follow through on.As a result of these promises I did not pursue other great offers from Vodacom's competition. She had promised to get back to me on the Monday and I even phoned to try and get back to her myself and left a msg for her to get back to me and still didnt get a call from the agent who promised me my new deal would be completely taken care off. My call has been recorded which will verify these promises made by her and those to follow who I contacted afterwards. Which shows Vodacom avoiding be answerable as after this event I have contacted a manageress at vodacom cancellations department and also a team leader of that department who all further avoided contacting me as a result of Vodacom not following through on their word which obviously stems from high up in the hierarchy too. Proof will be seen by the recorded conversations. I am extremely dissatisfied and frustrated at the way Vodacom treats their loyal customers and will not stop until the matter is resolved. I have further contacted vodacom cancellations today and the manageress still is giving me run around and avoiding my call even to date.
