I have to pay more for the same product I tried to order 2 weeks ago because Takealot *****ed up

So i ordered an LED ring light on takealot about 2 weeks ago, it was on a massive special for R700. I already paid and everything. Today I get an email saying "Takealot has canceled your order due to supplier shortage" So I have to wait almost 3 weeks for my delivery, while they're just handing it out left and right? Now all of a sudden the suppliers don't have stock? I tried to contact them but can't phone cause their phone lines are down due to Covid-19. So I tried emailing them but that doesn't work cause they only have automatic response emails. You can always go to their help centre which is pretty pathetic. Now I have R700 credit cause they can't give me a refund and the cheapest light I can find now is R1100. So I have to pay more for the exact same thing because they *****ed up?
