No collection of a return

I purchased shoes from takealot and besides the fact that the shoes doesn't look good at all due to the one shoe actually being bigger than the other one (the problem is not my feet), they were delivered late. Then I logged a call to return the product immediately. I got a call two days later to confirm that collection will take place on Thursday before 14:00. It is now Friday 13:27 and still no sign of Takealot.... Now, I would like the shoes collected and my account credited as soon as possible. I am a loyal takealot client. I buy everything I possibly can from takealot. If they sold bread and milk, I would probably have bought that too! I just find that the service lately has been shocking and not what I am used to at all. I am actually considering finding another online retailer.
