Expired g****tisers

I bought 2 bottles of the white g****tisers for dinner and they have expired. The expiry date is actually the 02 April 2023. I am beyond dissatisfied as I had to now go to the nearest garage to spend money on another soda drink so my family can enjoy dinner. Coca-Cola_g****tiser asseblief attend to this matter with urgency, my 3years old has already started drinking it while he kept on saying "it's bad" I can't seem to get the off taste from my mouth either and I hope this will not affect our health somehow. Thank you!
