Shocking customer service

My 14yrs old son and me went into Homemark store to purchase a drone. They were helpful in selling a drone to us. The next day we wanted to return it and were told we couldnt as they dont refund toys. The gentleman said that it was against there policies to refund us. I reminded him that he failed to explain there policies - return policies if we were not happy with our purchase. He then shows me a small photo copy of there return policy . Then he adds that toys are not included on there return policy. I showed him on the box that no wear does it state that its a toy. Please can you assist us in this matter. My son bought it with his own money. Freddie van Rooyen ********** 765 **********
