Missing items from delivery and no communication

I made an online purchase from Leroy Merlin which I have paid for. The delivery come on Friday the 17th. My paint was missing from the order so I called immediately and was told they would give me feedback. I then wrote an email and I got the same message that they will check with the store in question and give me feedback. It is now the 21st and I have had no feedback at all! No one is communicating with me and I have already paid for the products which cost over R1000 that I'm now out of pocket. All I want is some feedback and to know wether I'm getting my product or getting my money back!
