Takealot tumbles as they rest on their laurels

I am a more than regular customer at Takealot. I spend an enormous amount of money with them all the time. Lately, I am finding that they are dropping the ball. I know that the Black Friday / Cyber Monday and Festive season are all putting excessive pressure on them, but they don't seem equipped with the infrastructure to cope with the influx of business. They should be well prepared, knowing what to expect. I ordered an Android Smart 40" TV, and the driver parked way down the road when the order arrived. I had to go to his van to fetch my order. The TV was only one of the products. The driver said it wasn't part of the order. I insisted that it was and got him to unpack his van, and there it was. I brought it inside, and the box said 40", but my spouse said it looked smaller than 40". We took it out of the box and measured it, only to find that it was 36". We feel cheated and ******. I contacted them, and it just wasn't adequately dealt with. The customer service skirted the issue and acted dumb. I feel irritated and frustrated as they are not getting my point or pretending not to. It is difficult to deal with them as they are not addressing the issue. They are willing to collect and refund me. That is not what I want. I want a genuine replacement of a 40," but they will merely send the same box back. That is false advertising. I told them I would want them to measure the TV, but they are playing dumb, so the communication issue is a problem. I feel so **********.
