BAD SERVICE OF NO STOCK AND NO DELIVER!

I'm not hifi corps biggest fans right now! I purchased a defy stove online more than a week ago last month on the 28th of January now going for 2 weeks.Upon making the purchase online there was no indication that there is low stock or no stock available, purchase and payment went through, I tried tracking it and all it could show me order placed successfully, I contacted their online chat dealt with a Chelsea and Deon and they couldn't give me clarity on what the issue was only that there was a problem with the delivery, a fault was logged with complaint number ***, I get an email telling me that they apologize for the delay as they are out of stock of this item!!! I'm not impressed why is a product advertised on the website when there is no availability of this item and they have NO NO ETA available , and upon telling the service adviser if this is the case then I want to rather cancel my order and take my business elsewhere so they will need to refund me I was then told I must take it up with customer care and I will get a refund within another 7 to 10 working days! Yet when I made the purchase the payment went through immediately, I have never dealt with such *********** people before, with such false advertising, what are they doing by taking out monies yet they do not have stock of the item are they using our payments to buy there stock!! this was supposed to be a surprise for a loved ones birthday and now the SURPRISE IS JUST SPOILT!!! If I could rate this service a ZERO I WOULD!
