Half empty box of grandpas

On Saturday 9 June 2018 I bought a pack of 25 Grandpa's from our Spar When we opened the box half the small Granpa packs were empty and the other half there were barely anything in them This is very sad as we buy Grandpas regularly as it is the only over the counter meds that helps for my headaches I have the batch number that appears on this box

Grandpas are getting expensive and this is unacceptable
