Sold food product that's not good.

My mom has bought Sasko bread twice at Boxer store in town Durban I can't really remember the street name but my mom will know it... So we have bought 3 last month and 3 last week.. We only noticed the problem with them when my mom bought them the second time, and my father did complain about the bread when my mom bought them last month and as she bought it again this time we all noticed it, it looks perfectly fine but when u touch it, it feels old and when u taste it it taste as if it Off but the date on it it's 20th we ended up throwing the bread...
