Missing Items and no communication

I purchased a headboard, 2 pedestals and a dresser in the beginning of February. Only the headboard arrived. I went online, and used the 'trace order' it takes your details and advises you will be called back. This never happens. I called the Customercare number, they also advised I need to call the store I bought it from, which is Stroneridge. When you call Stoneridge, the call doesnt go through. I called 'Customer care' back to ask why the Stoneridge number doesnt work, she said she will get them to call me back. This never happened. She then gave me 2 email addresses to email, and ask where my order is....still no reply. I think its completely and utterly bizarre that Cielo's customer care is basically a switchboard to send you to other channels. (Shouldn't they actually accept a query and handle it?) Equally crazy is that none of these people are contactable nor respond. May you kindly advise when I can expect the rest of my delivery? Its quite unfair, that I have already paid an installment, yet I’m not even using half the furniture???? If I do not receive my items by the end of next week, I will advise my Bank to decline my debit orders. I am no longer paying for something I do not have possession of.
