No Delivery after payment

On the 11 August I purchased an item for which I paid for as well as delivery. AI was promised delivery the next morning by the floor manager. I phoned a number of times yesterday and was assured that the item was on the delivery truck and that it will be delivered. Today I again phoned and was informed again that the item is on the truck and that delivery will take place. at 14H00 I phoned and spoke to a woman who informed me that the item was still in the delivery section waiting to be picked up. I am a chronic epileptic and am home bound and disabled to this condition. I cancelled a doctors appointment yesterday and today and will have to wait until for a cancellation in order to acquire another appointment. I have informed Game of this and as such the delivery is important to take place when promised. I have emailed their complaints line as well. All of this seems a fruitless effort, and the customer service in this instance proves to be extremely poor. Still holding my breath for delivery as I cannot drive to the branch to enquire, due to my condition, .
