Selling Products under false terms

I got a phone call from a Mondo sales representarive offering me an additional data contract to my Vodacom contract because she see's that I am loading more value in data bundles per month than the subscription of the extra contract. This then should, according to the sales lady, save me money since I no longer need to load additional data bundles on my Iphone contract. I was immediately intrigued as this can save me money. After that it even got better since she will also include a Huawei router into the deal. I then asked more than once if I will be able to use the 2GB of data directly on my phone, and not through the router, more than once I was reassured YES! When the package arrived and my 2GB of data was not on my Iphone, I called Mondo, the representative then told me the data is only available on the router, contradicting what I was promised. Based on this I cancelled the contract, and paid now for two months for a contract I did not use (package sent back sealed) because it was sold to me under false pretenses. My Fellow users please be careful, and do not take contracts out under false terms from Mondo, it will inconvenience you and cost you dearly.
