poor service,bad attitude,rudeness

Precious at Pep Mokopane store 5545-005 has bad attitide,she does not smile,she is rude,she is not friendly and has no appreciation for clients.Im using a crutch to walk and I went to her to ask if they have mpesa,she did not even look at me.This is not the first time everytime I go to this store she is always rude,always looks tired.Today I asked her why she does not smile and she said thats how she is,it's her nature,what happened to customer service?And doesn't pep give disabled clients first preference to be helped,today I stood in a queue for almost 30 minutes to be helped while precious was busy chatting with her colleague. She was the only one working and she has no sense of urgency,Desree_im assuming its the manager was called to authorise a transaction and I asked her why only on3 cashier was working she did not answer me,she just looked at me and proceeded to authorise that transaction she did not answer me as if she did not owe me any explanation. Im disappointed of the level of service I get here,so ridiculously poor,please take them to customer services courses.I am so ****ed as I felt so small and disrespected as a client at pep like I do not add value 2 your store
