Excruciating customer service

Hello. I bought a Sansui bar fridge from Bradlows in Birch Acres (Tembisa Mall) on lay buy in December which costed R1600 + R200 for delivery. I paid R1400 in December and then paid the other R400 in mid January as I needed the fridge for when I move in to res in February. To this date it has not been delivered. I have been sent from pillar to post. If they're not claiming they don't have stock, their drivers are getting lost when they come to deliver but not even once have they contacted me to inform me about all of this, I always have to call the salesperson who assisted me and sometimes I get ignored. What upsets me the most is that yesterday when I called the salesperson she said they're missing a copy of my ID, if that is the case why didn't they ask for it when I paid better yet, when they claim that the delivery people are getting lost didn't they realise then that something is missing? It's easy for them to accept cash but hard to deliver. I regret walking into that store. Right now I don't even want that bar fridge anymore. They can keep their fridge and lies and give me back my money.
