Still natural spring water smells of motor oil

Purchased a six-pack of 500 ml Aquelle Still Natural Spring Water at Checkers on 29 September 2018. My daughter opened one of the bottles and complained that the water tasted foul. I opened another and found out that both bottles had a distinct smell of what can best be described as used motor oil. Aquelle is clearly not interested in quality control / assurance of their products and most likely also not in the well-being of their customers. Steer clear!
