House and home gateway has the worst customer service

I would like to start by saying house and home gateway is the worth store to shop at the management there is the worst I've seen. My complaint is about a fridge I purchased from house and home gateway. The fridge gave me issues were a technician from KIC came out and told me that it's either they replace it or give me the cash back. It's taken them almost a month to let me no as to how long the credit last. So on the 29th of February I dropped of the fridge at the warehouse. To my surprise the guys there say they have no idea about me bringing a fridge there after making arrangements with bongiwe an sipho from the store. Leon calls back an say leave the fridge at the warehouse and he will call me back the next day. 5days later and his still calling, 5 days later an house and home gateway still haven't paid me for the return of R4000.. This is how a company falls when u have clowns running a big operation
