I am a mother of a 2-month-old daughter on the 2nd of May I purchased a tin of Alula gold, from Rosebank checkers, I was disappointed today when I opened the tin of milk it had already been opened, this is a health hassard.I unfortunately do not produce breast milk so me opening the new tin means I immediately need to feed my daughter. Instead I need to go back there again travel with my own funds, mind you I'm on maternity and I cannot afford these back and forths.I have never came across such a disgusting experience I should be enjoying being a new mom instead I'm being frustrated because of this horrifying experience.
