Water worms in Woolworths Bottled Still Water

I would like to express my disappointment with Woolworths Sunningdale Umhlanga, I have bought dozen of 1.5 Still Water Bottles, to my surprise that the water is dirty, is having unknown residues black in colour( water worms?). I bought the water yesterday the 5th October 2020 and drank 3 bottles of that dirty water, not noticing that the water has black unknown residues. At night I had a headache from no where only to find out the following day that the water I was drinking was dirty. If you need a proof of the water, I did took a video of that dirty water with black unknown residues (water worms?) If you consider buying Still Bottled Still Water don't buy it from Woolworths
