Takealot red-flagged

So angry. I'm unable to make a payment to Takealot from my debit card because Takealot has apparently been red-flagged. So when I called the Customer Care Centre, from my mobile, it was suggested that I go to Secure Chat on the app. I duly did this as I am a pensioner, and only have a R49 contract with Vodacom. I was then 132 in line for Secure Chat. There is no sound when they come back to you, so when I rep**** I was suddenly 203 in line. So back to the Customer Care line where I was sent from pillar to post, and told that someone would have to activate the payment for me. After 45 minutes on my mobile I had used up a whole month of my airtime, and had got nowhere. Why did FNB not notify me that Takealot had been red-flagged? How do I make a payment to Takealot in future?
