Sleepmasters Not Returning My Money

I purchased 2 Perth Queen sized beds online towards end of May, a week later I'm told that the beds are unavailable and it was a system error as the bed was discontinued.... I requested a refund instead of ordering a new bed and last week Friday 3 June I get a call saying the refund is processing... yesterday I follow up and I am told I will get the Money shortly but still nothing, Helen Naidoo is the lady that has been responding on email. I am utterly disgusting by the major delay in getting my money back.
