Made an appt nine days in advance for a Covid test. At the time I had insurance coverage. Before my appt I changed insurance from what I listed with CVS. When I arrived they told me they could not perform the test due to no insurance. I offered my new insurance and also showed their website showing no insurance was required anyway. The staff was rude and aggressive and said they didnt care what their website said and refused to let me speak to the manager. User's recommendation: Do not visit the CVS site in Hesperia, Ca on Bear Valley Road!
