Worst experience ever received

If there was a zero rating, that was what I was going to rate. I bought a car seat, and was given the wrong colour. Seat was R4999. Bought it on 2020-12-04 , I phoned on 2020-12-07 to inform them. The attitude I received from the manager was so awful, I fail to understand how she leads, when she needs leadership herself . She listens to reply, I told her I was given the wrong colour, the first thing she said was she does not do refunds or exchanges. When she eventually heard what I was saying, she said , she cannot give me the refund, as she did not have such amount of money in her store. All I wanted was an exchange for the right colour. I went to the store, a lady came and said she was the assistant manager , and that the person I spoke to is the manager was busy. She promised to look for the seat in other branches and promised to get back at me, I asked if I should return the seat, she said not until she gets me the correct one. I have been waiting since. I went on Saturday the 12, same lady who is apparently the assistant manager, told me she was off on the previous week, and offered to give me a discount on the seat which is on display, I said no. It’s the same seat I wanted originally. Till today nothing has been done, I will be taking Toys r us to consumers right, if this is not resolved within this week, in fact, I am no longer interested in doing business with them , I would like my refund, I have given them enough time to resolve this, I am tired of dealing with an *********** person.
