Vodacom *********ly sold me a twisted one sim P8 instead of advertised dual sim P8 light

Vodacom has sold me a dual sim Huwai P8, but *********ly has blocked the second sim and has kept it secret from me when I was buying the phone. I bought this phone simply because it is a dual sim. The sales person at Dealz Somerset West (from where I bought the phone) also assured me that it is a dual phone and it will work with a second sim card of any operator. However, Vodacom has blocked the 2nd sim, making the phone practically one sim. Neither Vodacom nor Dealz has informed me that the phone is practically single sim. Instead the phone was advertised as dual sim and, they still sold it to me as a dual sim. This is deception and treachery to the customer. Although I have paid for a Dual Sim P8, I was **** to and sold a twisted Vodacom junkie instead of a decent P8. I request Vodacom urgently give me a decent Huawei P8 with dual sim working properly because I have already paid for it. I also request that they should publicly apologize for deceiving the public in this manner.
