Money rip off

On Saturday i took my family on shopping at the mall and one of the Vintage Photography agents approached us to take photos so we decided why not, so upon booking for an appointment i specifically asked that agent by the name Kay that we are only interested on getting digital copies of our photos so we payed an amount of R200 to take pictures then after the photo shoot the photographer starts to explain and show us their packages that which they wasted our time and money to realize later that there is going to be additional charges to get our photos, my main problem with that enterprise is why do they let you go take pictures before explaining prices and why did their agent confirm that im going to get my digital pictures by just paying that R200. I need to get my pictures on digital format can the management of the enterprise do what is right please.
