Kroger review: Pharmacy

I needed a prescription filled 01/29/21 at Kroger at 3444 plaza avenue in Memphis TN . I had a manufacturer coupon (2 of them) it was clearly written on them that both could be used at the same time. The lady named Angela who was working the register told me I could only use one. I told her that wasn't true she went to ask her manager and came back and started saying that it was going to take a long time. I said "that's fine but had she resolved being able to use both coupons?" She was upset and said " sir I am trying to tell you how long" I said "ma'am I'd like to make sure that I can use them both since that what we were talking about before" she threw her hands up asked if another lady could take over and walked away without saying a word. It was super rude. I will not use Kroger's again.
