Poor service

I bought the Betalin syrup from clicks cosmo city mall yesterday,I already had 6 s****s,i olny saw expiry date today.I called store asked to speak to the manager Otlametse,some how he said the medication even if is expired it’s doesn’t have side effects.oh!why do they put expiry date in the 1st place,stop playing with peoples health,meaning clicks sells expired stuff always,I’m very disappointed in you guys,I’m thinking of getting medical test.😡😡😡😡😡😡😡😡😡😡😡😡
