False Advertising

I purchased the P30 lite from Vodacom, the main reason I chose that phone was for the dual Sim card. And to my surprise once I received the phone on the 28th Feb, that can only read 1 Sim card, this was never advertised nor did the sales lady at the Greenstone store tell us. It's no where on their website or pamphlets. This is false advertising, and if that's the case, can Vodacom unblock the second Sim slot or rather cancel my contract so I can go purchase at another service provider where I can get what I paid for, I'm not willing to change or cancel the current number that I'm using because the phone I bought (which is meant to read 2 Sim cards) is not able to read 2 Sims due to the service provider that I use. This is ridiculous that I must pay the full amount while the device I'm using, which is capable to use both slots, is only using one. Why are we being **********, surely it's my right to get what I pay for?????
