Tropika c***** juice

I bought the tropika juice from shoprite, when I open the juice there was black stuff and the juice look like it was not mix properly. I then phone c***** to inform them about the juice not being safe to drink and they compensate me with a R40 voucher, which I think they can do beter. Cause what if one of us had drank from the juice and landed in hospital, do you think R40 would cover the medical expenses.
