Bad service at Lewis Alberton

So I purchased a wall unit at the Lewis store in Alberton and wow its a week later they still haven't delivered it yet.

We paid this off over a period of two months so it is fully paid but still hasn't been delivered. When I called last week they told me that they have stock and they are just completing the transfer forms but its a week later and no one has said anything. Also one of the employees kept telling my mother that she needs to pay a delivery fee of 400 rands in cash meanwhile the other said we wont be charged for this - it seems so dodge that the employees are telling us different stories.

Not happy with the service at all.
