Disappointing Customer Service Experience!!!

I recently visited Van Schaik Bookshop in Rondebosch looking for assistance with a No. 18 Green Number Sense book but unfortunately I was disappointed with the service I received. I did not have the ISBN number and instead of trying to assist further or offering alternative ways to search for the book, I felt dismissed. I understand that ISBN numbers make searches easier but customer service should still involve a willingness to help where possible. The interaction left me feeling unwelcome and unsupported as a customer. I hope the shop improves its approach to assisting customers in future.
