Double credit and no bed

I made a purchase for a bed on 11 October. The mattress warehouse website returned an error however on my side the payment went through. Thinking there was a problem I made another payment, same problem. I contacted my bank and they sent confirmation in the form of a proof of payment that I sent to the mattress warehouse. I called numerous times to follow up and I was promised a call from the sales director Zaani Smith. I called the customer service center numerous times and finally got hold of Natasha van Heerden who promised to help. Unfortunately more empty promises.

It is 5 days later and I still do not have my funds returned or a bed on order. I keep getting empty promises. Do not purchase from this company, rather go to a store. They do not have the capability to run an online business. I am hoping that my double payment is returned.
