Takealot service is very poor, annoying and tiring. I placed an order on Sunday then paid on Monday then to my surprise my the payment confirmation took long so I had to email and send the copy of payment, the next morning that's when I received the confirmation of payment and the email showing that my order will be delivered on the 11th. To my surprise I went to checkers if the order was shipped or not but saw that my order has been cancelled and immediately received a cancellation email, I then sent an email wanting to know the reason why my order was cancelled after the effort I took trying to get tgem to do their job. Im so furious right now, how do you confirm an order and then cancel without notifying the client right now I'm still waiting for feedback from the warehouse since yesterday at 4pm
