terrible service

im really unhappy with the way i was recently treated at pna stationers greenstone. i was looking for a txtbook for my son whois in grade 3 and i phoned them to find out if the they had the textbook in question but the lady i spoke to was rude so i let it go assuming that she was stressed being the beginning of the year and all so i called again 3days later and i spoke to a different who was more helpful and she told me they have the book and that i could come and collect it so i said i would come on friday when i knocked off from work she took my details and said i could quote my details when i got to the store. friday came and i went to pna and i was helped by one of the trainees who then called one of the employees who took forever to just go to the back and when she did finally come she said my book wasnt there and that if i didnt know who i spoke to about fetching the book on friday then she also cant help me so i asked her to check then she said they are the only pna with the book im looking for and she doesnt know when the book would be available without even checking with your other pna branches so i left because now i was annoyed that 1 person said the book was available and another person dismissed like i was some sort of idiot. on my way home i got a call from the same lady that had dismissed me "Émily" saying that she had found the book that i was looking for so i went back to pna when i got there i asked her where was this book now coming from because earlier she said they didnt have she simply said just be happy that i called you back and thank me instead of asking silly questions and take the book and leave so i also did as i was told but i was unhappy very disappointed in the service that i got at pna stationers this week.
