Disgusting service

I.have purchased a LG toploader washing machine from takealot, about 5 months ago. The washing machine stopped draining the water and I contacted takealot, I told them that I want a replacement not a refund. The machine was picked up on Monday and Wednesday they refunded my takealot account with the money and advised that the machine is out of stock. I went online and they.have the exact same machine, so the price is higher. I contacted takealot and opted for the Samsung or hisense toploader, there is a R1000 difference, upon speaking to the customer service agent he said that they would write of the R1000 and deliver the machine on Friday. Today I went onto takealot and he just put the washing machines in my basket. They promise to call or sent emails and yet nothing. I am really disgusted with their unprofessional ethics.
