Devious MTN Sales Practices

My MTN contract had expired and I was on a month to month basis. They were hounding me to sign a new 24 month contract. In the end I caved and signed a new contract but did not request a new headset so there was no real benefit in my signing the new contract. However, the consultant persuaded me with some benefits that I can't even recall or did not perceive as such. I just wanted them to stop hounding me. She assured me that I would not be disadvantaged. However, lo and behold, after being on the new contract for a month, I saw that the data available to me was 13Gb. I had 46Gb prior to signing the new contract!. So much for a benefit to me. Maybe she thought I had shares in MTN.
