The Home Depot complaint: Rude and condesending employee Terri at the customer service and online order pick-up desk

I came in to check status of a recent in-store purchase that was to be delivered to the store. Employee Terri immediately said in a louder than normal voice Did you get an e-mail telling you it was ready to be picked up? I calmly answered that I did not check my email every day and whie I was there to buy some other things for my bath remodel and wanted to see if it had arrived. She almost shouted at me then that I will get two emails one saying it had arrived and another that it was ready to be picked up. So I took out my phone and said well let me check and see if the email had arrived yet. She then said Let Me look it up I can find before you can even begin to look as if i was inept at checking my emails . I felt very unwelcome and insulted by her behaviour. She should go back to training on customer service and how to treat customers with respect.
