Poor Service for Faulty Goods from Takealot.com

I have purchased quite a few sets of Christmas decoration lights from Takealot.com way ahead of Christmas to make sure that I have everything I need in time. I have received all goods in good order except the one set was faulty. I have arranged a return for replacement and that was very easy, until they had to collect. I have received a text on Thursday,13 December to advice that the collection would take place on the following day, Friday 14th. I had a lot to do but decided to stay home until they come and collect which did not happen at all. Today I contact yhem through tbeir Facebook account to inquire. They then advise that they will collect today or tomorrow but can't confirm as they are very busy, I have then advised them that I will be working and won't be available at home to see to the collection. The agent then tells me that they can't change the address for collection and that I must make sure someone is at home. This is pathetic from their side to say the least. I will think twice before placing another order from them. I will contavt the CPA in regards to this as well.
