Marketing under false pretences

Misleading advertising! I received a call from a someone named mansoer who declared to be a snr sales person who can assist with financing me a taxi. Someone else calls the next day who is mansoers understudy who inform me now that they can't help me with financing the taxi and I first need to pay half the money in cash brakenfell western cape and if I don't I should go to sa taxi.

So I am fine with looking elsewhere but why promote and advertise false information nowhere in the add does it say you have to pay 50% in cash before you can be assisted
