Bad service

I went to shoprite at lakeside today to buy huggies gold,cerelac 500g and purities but they didn't have they only had purities so i decided to leave to go to another shoprite where they have everything only to find the rudest security officer accusing me of *****ing a spray simply becouse i ddnt buy anything and her colleague also came nd also added that i stole purities which were not in my handbag there was only a spray which was half i bought long time ago they said there supposed to put a sticker which i ddnt know one 1 told me abt it and it wasnt written anywhere they should just hire new security officers as the ones they hire they do not know what they are doing am definitely not buying there again
