Bad service from Romans Pizza R55

Yesterday we ordered some pizza and a chefs salad from Romans Pizza At R55 through Mr Delivery. When i got my order, it wasnt a chef salad but a normal greek salad with lots of olives that i cannot eat. However, i did phone them at around 19:45 to tell them about the mishap. The guy that answered was rude over the phone, he took my phone number and said he will get back to me and then he put the phone down in my ear. Never heard of him again. After about 15 min of hearing nothing my husband called and he was quite rude to the guy because of how he treated me. The guy again put the phone down in his ear. Needless to say I didnt really eat anything and i am quite dissapointed in the service we recieved. We are paying a lot of money for food and that is how we are treated.
