Daylight robbery

We booked their service to move a pizza oven from the front of our house to the back of our house. We were told to pay a deposit of R1500 to make a booking. Yesterday the movers arrived and said they don’t want to move the oven as there are too many stairs. They said they will give me the deposit back. Today we found out that we will not be getting our deposit back. They are sharks! They will charge you for a job and then not do it. Daylight robbery.
