Unhygienic actions - Need to be stopped

I have recently purchased Nescafe coffee from the Southdowns store, and upon opening the bottle lid, noticed that Pick n Pay are opening the bottle lids to place a security anti theft strip in the lid. In so doing, the fresh foil seal of the coffee was opened completely. Whilst I find this totally unhygienic, I also find it totally unacceptable. Food & perishable Products should not at all be tampered with in this manner. This is not the first time this has occurred, however on previous occasions the foil was not broken and I thought it may have been a once off , however this time I cannot leave the situation which is a massive health risk opening for the spread of disease. I have an unopened bottle of the 2 I bought. Kindly intervene and stop this procedure before someone becomes seriously ill.
