Takealot poor service

In my most recent purchases with Takealot I have had quite a few problems.

1. I bought a product, after two weeks I was informed the supplier cancelled due to them being out of stock. It again showed they have stock so I reordered the item. I am now trying to cancel as I have waited too long, but they are telling me that they first need to receive the item before they can cancel it. This can take another week or two. I have not received the item yet so why can they not just cancel it and refund it.

2. I requested a invoice as I bought a few things for business purposes and needed to claim the money back. I was told I could not get a invoice until the items are delivered which took two weeks. Why can I not get a invoice if I have already paid for the goods.

3. I returned something. I was home but Takealot sends me a sms saying they could not get hold of anyone at the premises. They did not even try to phone me. They just left. Now I have to wait to be rescheduled.
