Extremely poor service from Decofurn

On 19 April I placed an order with Decofurn for the amount of R8565. Order number 351755. With lockdown and only being able to deliver some of the ordered goods on level 4, the 4 hanging dome lights and the 6 emma wooden leg chairs, were delivered on 12 May 2020. On 15 May 2020, I received an email from them that government lifted restrictions on delivery of online orders. On 22 May 2020 I received another email saying they have high volume orders and delivery of balance of my order will be few days late (I am still awaiting delivery of 4 x vegas luxury barstools and a double Sandhurst Retreat mattress). On 8 June, after not hearing anything from them again, I sent an email asking where is the rest of my order. Only to receive an email today, 12 June, from Sau****a saying the order was delivered and signed for. Just that and nothing else. When was the order delivered? And who signed for it???? Because it sure wasn't delivered to me. And even on my profile on the Decofurn site, my order still shows as in process. I find the service extremely poor because clearly if my query was investigated, this person would have seen I am talking about the balance I am waiting for. I have been more than patient in waiting for my orders, but this is nonsense. I want to know when I I can expect my furniture which they owe me, for which I paid a lot of money!!!
