Defamation of character,PICK n' PAY cradlestone mall

Defamation of character I always buy at pick 'n pay in cradlestone mall,On this day after paying,A pick 'n pay employee came to me and told me that they have been monitoring me through a store camera, they say I ***** everytime I go there ,I even asked the manager for the footage of all these accusations, they couldn't show me , I even phoned their head office and they promised to attend to the matter , I went to the store the next day only to find out that the woman say she was playing with me , and I am not here friend , and I do not know her, I am deeply hurt and feel so abused by pick 'n pay, I no longer buy from pick 'n pay, l am opening a case against pick 'n pay and that woman , I'm telling you my lawyer will deal with you
