CUSTOMER (S)CARE SERVICE

I bought a fanta 500ml buddy at pick pay, led by assumption that it is pick n pay, I didn't check the expiry date. To my shock when i got back to the office, i shared same with my colleague and.... what a bitter sweet taste. The smell was pungent and she then check the expiry date only to discover that indeed it had expired. We took the drink back and all they did was give us our money back. What was R10,00 compared to ones health..... We have been suffering from diarrhea since last night and when they were advised, they told us to go to the GP for consultation as they require doctors certificates for proof..... REALLY???
