Bad tasting Crosse & Blackwell Mayonnaise

What is up with the awful new taste of the Crosse & Blackwell mayonnaise? It does not have that fresh, tang flavour anymore? It tastes rancid! It also tastes like it has some sweet taste that was not the original taste. The texture is also very runny and the colour is off. I bought the mayo at Spar and thought it was tasting bad due some production or storage issue, but then I bought it at Checkers and OK, and it tastes the same! Why did you change the product from its original taste and texture? It really tastes disgusting and ruins salads and sandwiches. It's very unpalatable. I refuse to buy this product again.
