Disappointed regular customer

As a regular customer of takealot, having purchased dozens of items, I purchased blinds which were supposed to be a specific size for my patio. Not only did I receive the wrong size item (shorter and cheaper item) I was not informed of the swap. I contacted takealot to ask for a replacement to which I was told stock was no longer available. I subsequently requested a return. The item was purchased on the 05/12/2015, delivered on the 9/12/2015 and the same night (9/12/2015) I requested a return. I phoned everyday and the pick up only happened the following week, and we were told the blinds were too big. Then I had to phone again, multiple times, to be told by takealot on 23/12/2015 to contact the couriers who said they would only get a truck on the 28/12/2015! So I must wait at home, until 5:30 pm for the pickup for 3 weeks only to be told it would be picked up after Christmas. All the while I have to wait for my refund because the items were still with me. I was told I would get a refund for the one item which I still have not recieved. The poor management that I recieved, updates that never happened and the many calls I had to make for this has left me very upset and disappointed.
