Tomatoe sauce rotting before expiry year, for the second time!

Again I've been brought to much dissapointment by tiger brands. After last year's inccindent with the "all gold tomatoe sauce" ; I was adement not to buy it gain, the one I got from their R40 voucher didn't give me issues. Last month I bought a bottle of the all god tomatoe sauce cause my son asked me to, to my surprise again the samething occured with this bottle, it's bubbling and smelling sour, the contant is half and there's no direct heat coming in the cupboard. Clearly it shows that the quality of the product is poor and again expire shows for 2023. I don't even want to contact them as they took a full month before a consultant called me, which they had done so after seeing my complain on hello peter. I'm done with this brand, their customer service also sucks.
