Poor customer service

So we went to Fair price at Cosmo City to buy a queen bed and a blanket box and bought them cash the problem encountered was when the delivery guys came to us to deliver, they delivered a damaged blanket box but promised that they will come back to fetch it. We even sent them an access code cos the said their going close by to deliver some items. What they did without our consent is that they scanned the receipt of which they shouldn't have. So this afternoon we phoned fair price customer service to ask when they going to fetch the box but they said the box appears that it was delivered in a good condition on the system. We tried telling them what happened but they never took it instead they were arguing with us on the phone then we phoned the driver now he's also changing the story. Now we are stuck with a brand new damaged item from Fair Price. They are not even willing to exchange it for us instead their shouting at us just to cover their tracks. But otherwise this box we are taking it back to the store if this matter can't be resolved because of HQ poor customer service we don't have a choice but to escalate the matter to our lawyers. Please fair price sort out your customers service towards your customers and sort this matter out ASAP
