Delivery Missing Items and No Support

Part of an item was missing from my order, the base of a Standing Lamp Set was not in the delivery, leaving me with a non-standing lamp that I cant use. I submitted a email query and heard nothing, not even a confirmation that my query had been received. A week later I emailed again and tried the live webchat option (which alleged to be responding within under 6 minutes) but over an hour later there was still been no reply, I then tried the whasapp chat and was told a query was being logged with the warehouse, that was another week ago and still no feedback. This is the third time I have received an order missing a part, once it was a entire couch cushion and a few months ago the top glass cylinder of a Hurricane Lamp was missing, anyone who knows what it is will know its pretty useless without the top (about as useless as a standing lamp without a base stand), on that occasion I was also told it would be sorted out but never heard from them again. All I want is to get the missing parts. I wouldn't recommend anyone using their online store or delivery service as its not reliable and when you need their support you're left feeling completely unsupported!
