Bad and worst customer service

My mom bought a fridge at game okay we laybye the fridge now we finished up paying for everything before time then we were told that they don't have stock and they don't reserve items on laybye but we weren't told about that from the onset okay we have been waiting the manager told us that they'll deliver after 16 Dec on the 18 Dec but we still waiting for the fridge on Sunday 22 Dec we got a sms saying the fridge will be delivered on 23 waited for nothing because no communication at all now the system is telling us about DC must confirm the order actually this store is not to be supported poor customer service and communication guess I'll tell my mom that we need to collect our cash and by somewhere else because their customer service even at the floor their guys don't know how to deal with customers...
