Walgreens complaint: Being Hung-up on by Walgreens Pharmacy

I have been trying to get diabetes supply’s Test Strips lancets from the pharmacy. About a month ago I went in to pickup and they said my co-payment would be over $100.00. I mentioned that I had Medicare Tricare for life Insurances and I’ve never had a co-payment. It appears that they did not bill Medicare and only bill Tricare. Which Medicare is my primary. They told me they would call Medicare to see what the problem might be. I called Medicare on 15 Aug. 2022 who suggested I call the pharmacy to see why the $100.00 charge. They said because of Tricare. When I called Walgreens pharmacy and the same mentioned date, they first told me that they had received a form my doctor that they had requested over a month ago, and after they said they would get my supply’s ready that they would call Medicare to see what was going on with approval. I received a phone text on 17 Aug. 2022 stating that my prescription was delayed because of being to soon to refill. I then called Walgreens pharmacy and told them I had refused to except the refills because of the co-payment of over $100.00 that i had ordered strips from Amazon for $28.00 was on my last strip. The male pharmacy person stated that he wasn’t aware of the text, and they had no way of knowing if Medicare had received the form from doctor or not. They pharmacy hang-up on me
