Very poor customer service.

Good day I would like to report a bad service received from Spec savers president hyper Powerville by Hazel, I have been a customer with their company for the longest time, but service received today was really bad, I called in to ask for a frame number of spectacles i previously took from them, the lady was really rude to me, while I was looking for a pen to write a number she shouted to me telling me that I should call her when I get a pen because she is working alone it the store, I dont know who's fault is it for her to work alone, her attitude towards me as a customer is really bad, I am also thinking of taking my business else where because she really has a bad attitude, her service is really poor.
