Hirsch lying about stock of a product.

We purchased a stove off the Hirsch website and paid via credit card. A generated email was sent to us with proof of purchase and payment and item was to be delivered in 2 to 3 working days. However now we get an email from Preline Moodley stating that this item is no longer in stock and no knew stock would be available. I have contacted both the Cape Town and Gauteng branches who both confirm there is stock. I then emailed Preline to notify her that there is in fact stock of the item and if she could be get it transferred to our nearest branch for delivery. Preline contacts me and states that I am incorrect and in fact there is no stock available and that when new stock does become available I cannot get it at the purchased price. Her attitude towards me when I stated that in fact there is stock I was made out to be a **** not withstanding that they still have R7000 of ours which has not been refunded. Not impressed at all
