Poor service-stock out

I would like to share a poor experience I had Takealot regarding a recent purchase made. I ordered a splash pool on the 2 Dec for R699 on special using my credit card. On the 3 Dec I received an email stating my order had been cancelled due to a stock out. The email stated that I must reply with my choice of refund option. I rep**** to the email asking if the product will be for sale later and why is it showing on the system that there is product available but now at R999. Ironically after replying I got an automated response stating "customer queries to this email will no longer be responded to". After that I decided to log a request using Takealot help option on their website. I got an email response several hours later. After several back and forth discussion I was informed that the product is available and I can order it for the same price. I received a credit voucher (which I did not ask for) and reordered the item. Only to be informed the next day 4 Dec that my order was cancelled again! I then phoned Takealot and informed them of my frustration and confusion. The person on the phone told me that the previous agent incorrectly stated that there was stock and only now the item has been removed from Takealot website. I requested that they refund me on my credit card as I wish to take my money elsewhere. The agent on the phone said that the system is not allowing her to do this but she will send me an email with instructions. I did not receive the email and when I logged into my account this morning I discovered that I received a credit note AGAIN! Even after I specifically requested a refund. Terrible service and their system clearly needs some work. Responding to emails that I get automatic response from stating that my query will not be attended too. Service consultants telling me there is stock and the website reflecting this. To asking specifically for a refund and getting yet another credit note. Poor service
