Appalling service!!!!!

I've been trying to order from HC for over three months now. I'm getting calls and emails everyday telling me I have credit of R20789. Two days ago I ordered the Coca bedframe with side tables of which when I called on the 21st I was told I needed to send through my proof of residence as I had changed my address online, hence the failed order. I was on the phone for 37 minutes with a consultant by the name of Valencia who helped me with another order. She then called an hour later informing me my order was cancelled again. This morning I placed another order online seeing I had submitted the required documents. I then decided to call and confirm if the order was successful of which I was advised that my coca bedframe together with the petite 2seater couch order was successful and I should await the order in 7-14 days. Knowing how pathetic the service has been, I decided to logon to my online account only to find that my order is not there again and one of the items I ordered is now out of stock. I logged out and refreshed the page in disbelief and only to find that I'm now barred. Even when signign on using the USSD code, I get an error to contact customer services. I am appalled at the service!!! I cannot spend all my time on the line with HC because of your incompetence! I am beyond frustrated and disappointed. If need be, let my account be closed off as I will not accept this kind of service and treatment... I am livid!!!!
