Incorrect Pricing Online - Will not honour purchase!!!

I bought some items on Black Friday promo ONLINE, the order was partially delivered by the earrings I bought were not delivered, the items I had bought as Christmas gifts were not delivered. I called on a few occasions and was promised the balance of my order was on its way. On the 23rd of Dec, my order was CANCELLED, the reason the item was not available, yet I could buy the item at a substantially higher price. I called on the 23rd Dec, spoke to Sindiswa after 45min call was promised the order to be reinstated, but then this was obviously just to end the call!!!! I then again called spoke to MIA on the 3rd January (ref no ***), was promised a callback but again no service from Game Online. It's pathetic service and won't bother to buy again online. Attached are pictures of the items I bought on Black Friday vs the price expected to pay on 23rd Dec. Game ONLINE you are ***** and false advertising items on the website!!!!!
