bad service

On saturday morning I went to wueensburgh malvern.Had my son in tow..bought groceries for more than three hundred rands.i was only gien one stickeez...but promotiinal item of robertsons spices had a stickeez poster on it..I didnt need it only got it because my kid wanted the stickeez advertised or pronoted by onp...enquired from teller who said definitely no.asked fir manager vanessa behaviour was in exusable..she was rude and condesening..rolled her eyes and said its only a stickeez...and I shouldnt expect pnp staff to know everything that is on promotion..she called marcus who as well couldnt help..the packer who overheard the conversation said it does carry the promotion..how embarrassing for pnp cluless managers
