Takealot.com Poor Customer Service

I have been trying to purchase from Takealot via App and Online for two week but each time I would like to pay, I get a response “there seems to be a problem with server”, I have called customer service twice who have requested that I mail screen shots of the error which I have done, it’s been over a week since the last report and no response from Takealot.... seems large volume infrastructure and sales don’t warranty the same scale customer service with internal system issues...
