Huawei P8 False product selling

Vodaworld has promotional Huawei people premoting the new P8,stating that it takes 2 sim cards, I bought the phone CASH just to find out that this is in fact a lie, the assistant store manager sold the phone to me and as I was telling why Im buying the phone, he at no point corrected me, Im so disgusted at the service and cant believe I support this network.
