CVS review: customer service

On Sept. 18, 2019 I went to this 24 hour CVS at approx. 7am there was no one to be found to check me out in the front. I looked around for about 5 minutes and the pharmacist was in the back by the drive thru window helping someone. After she had finished with her customer I did not asked her to cash me out, I only asked if she can page someone to the front of the store to help me. Her response was very rude, she told me very rudely "I will when I am finish what I'm doing". I understand if she was still completing a transaction at the window but she wasn't she had finished, how long does it take to page someone. The nasty way she spoke to me was very unprofessional and I just walked away. When I returned to the front of the store the cashier was finally in the front. I have no idea where he had been. Finally It was my turn to check out and now he tells me he can only take cash and it would be awhile till he could ring out credit or debit transactions because the system was down. My time was wasted at this CVS. I told him no I can't wait and I would just go down the street to Walgreens.
