Takealot has dishonest vendors an no longer trustworthy

I'm so unhappy with Takealot lately. Before one used to order and be able to see when things will arrive immediately but now it seems Takealot has let itself go and allowed dishonest merchants to join them. On 31st of January I ordered books and was informed of the late delivery but I didn't mind because the books were affordable. My stuff was supposed to arrive on the 19th of February but on the 17th two books were canceled and my money returned. After waiting so long the merchant only realised that late that they don't have stock? One of the books was my child's school book and semester had already Started. Now I had to start looking for a book 17 days later. Now again I ordered things. These I expected to be delivered within a week but a day or two later I saw that my order will only be delivered on the 17th of March. Isn't it a requirement by Takealot when joining that a merchant must have readily available stock. It used to be that the latest was 7 days but now almost a month goes by whilst we wait for things. I could have ordered my things separately it the merchant was honest from the beginning about the availability of stock I'm really displeased and looking for another app that can deliver on time with strict rules for it's vendors. Please suggest. I'm tired of the lies on Takealot now. It can't take 17 to 19 days for one to realise they're out of stock.
