CVS review: Covid testing 1

I scheduled an appointment on 8/8 to be tested on 8/9. I received confirmation emails saying "looking forward to seeing you" etc. I listened to the video of steps to follow and even received a text within one hour of testing time. I arrived at the test window on time and after waiting a few minutes, a technician with an attitude said "we are out of test and have been since Wednesday, see the sign?" I told her you should not schedule people to come be tested and know you do not have the tests. She said I should have received an email. I told her I did, and they said see you at 3:10. I thanked her for wasting my time. I think this is very poor service on the part of CVS. I will not be referring anyone to come to your stores.
