Cant pay.

I used to enjoy shopping on their site, as they quick with delivery & solved some issues in the passed, but in the last 3 items I've bought from them, I cant use fastpay or ozow, they both give me issues when trying to pay & I have told takealot about it, all I'm told its the website issue, but keeps happening & the only way I can pay now is woth card, which I don't really enjoy.
