Cheaper Contracts

During the month of September 2017 my wife was contacted by Vodacom and told that" as you are on a Smart S contract with us we would like to offer you a free upgrade to Smart S +. She compared the offer with the existing and found that It would cost approx R 40 per month less and she would receive more than twice the Data and twice the call time. This was great and she went for it. She has only been a contract customer for less than 3 years. I have been a contracted customer for about 18 years and went to sign up for the same deal. My existing contract is a Smart M and so I wanted to up grade to the Smart M + which does the same thing...double your calls and data for less money ....... the guys at the Vodacom shop said that this was not possible and I needed to contact Vodacom on the phone. When I did this I received all sorts of stories about why it could not be done. Im quite amazed that this type of customer service is so prevelent among the large corporations these days as it seems they do not have to suffer the consequences.
