Terrible Customer service

I went onto the homechoice website to check what good they have on sale.I am a previous homechoice customer with a paid up account and R16000 credit.As I clicked on a few items under SALE I noticed that a few items were marked as R2 CASH and different amounts under diff instalment options.I loaded a few things in my basket and contacted the call centre.(Currently still on the phone as IM TYPING THIS for 19 mins and counting)I asked the consultant why I had to pay delivery individually on these items.She asked for an item code which I gave her she returned to the phone to say it is a mistake ,immediately the screen went blank and the website had an error message.I asked her if I could speak to a supervisor...She said please hole and Im still holding ,while I can her her having a fat conversation in the background laughing...Please note that I have screenshots of the goods on sale and the sale prices as well as the items in my basket.I ALWAYS TAKE SCREENSHOTS WHILE DOING ONLINE SHOPPING.Can you please get back to me as I didnt even get a thank you for bringing this to our attention or anything like that ,was just kept on the line for 20 mins now.I will never purchase anything from you guys ever again,your service is disgusting and customer service reps disrespectful.
