aQuellé water off

We bought 6 5l bottles of aQuellé water and it smells and tastes horrible, and this is not the first time this has happened. I previously bought 3 5l bottles at a different supermarket which had the same smell and taste. At that stage I thought that it was the shop where I bought it, that it might have been old stock or stored in a warm warehouse, but there is definitely something off with the water. I'm really disappointed because I've always loved aQuellé.
