Very Poor Service and Uninformative shopping experience

I am EXTREMELY UNHAPPY with the level of service received from HiFi Corp.

I am trying to purchase washing machine from the online portal.

Limited Stock as advertised on the product does NOT indicate that NO STOCK is available in the Western Cape. Nowhere is it shown or advertised that a customer in Cape Town CANNOT purchase the item EITHER via Collection OR Delivery. In fact, after DAYS of shopping to compare products and prices we finally settled on this product, only to find out DURING THE CHECKOUT process that we CANNOT purchase this item. When I dialled the call centre at ***, NOBODY answers a telephone and I am informed by automated voice that NONE OF OUR SERVICE CONSULTANTS IS AVAILABLE. After 15 minutes of being reverted back to the answering service where I should choose my option, finally I get a voice message informing me: "You have contacted us OUTSIDE OF OUR BUSINESS HOURS" 11:36am on a FRIDAY!!! I called the nearest branch in Cape Town, only to be informed that "probably no store in the Western Cape has stock". Yeah, I figured that much, too late and after HiFi Corp wasted my efforts and time. Furthermore, I am informed that HiFi Corp does not do inter-branch transfers. This is ridiculous for a company that is trying to do decent business and provide an acceptable level of service to customers nationally. When I prompted the lady at the branch that why does the online not INFORM CUSTOMERS that certain provinces CANNOT PURCHASE the item, the response is "Yes Sir, they should probably do that..." Yeah, you probably should.... So, what is HiFi Corp going to do to provide me with the product they advertised, which I want, which I want to pay for cash, and have it delivered to me within 3 - 6 working days as advertised online??
