Takealot incorrect delivery and unable to provide item advertised

I ordered a laptop battery from Takealot on 16th January. The battery that I received on the 25th of January was not correct and did not meet the same specifications that was advertised (Specification of the battery advertised on Takealot =>4400maH and the battery that I received => 2200mAh).

Sent a notification regarding the incorrect delivery on the email address advertised on the website for complaints. However, this e-mail address sent an automated response telling me to use the online help options (which of course wastes even more of your time!)

Sent the online complaint on the 26th of January. Takealot responded on 27th January and promised to possibly collect and drop off the correct item within 24 hours.

6 Days later on the 2nd of February, I sent another complaint and phoned Takealot. Numerous e-mails later and after many assurances from Takealot that I will receive the correct item, I received the following notification on the 7th of February: "Please note that we do not have physical stock in our warehouse" So after making me wait for 2 weeks and promising on a daily basis that I should not worry I will receive the correct item that I already paid for and ordered from the official Takealot website 3 weeks ago, I am told sorry we cannot help you because we do not physically have the item available!?

Still waiting for the refund which I am promised is already processed but not holding my breath.

I would highly recommend not buying electronic / PC equipment from Takealot as they do not seem reliable and the staff make promises they cannot keep.
