negligence of customer goods

i have been harassed three times by the guards that work at pick n pay (the buzz) because they want me to leave my bag by the door. my main issue is there is no area that is clearly marked for parcels and this is a risk to our goods because anyone can walk out with a customers belongings. i brought up the issue with one of the managers who addressed me with a very sacarstic tone. he said the issue will be rectified after the easter holidays. i went in today and a female guard harassed me. as i walked out the guard by the door went on to mock me with regards to my complaint. can this issue be rectified ASAP because its unfair to have our goods put at risk like this. will pick n pay buy our belongings if something does go missing???
