The Walgreens on Division and 28th and the Walgreens on 28th and Kalamazoo are the two worst Walgreens. They have terrible customer service. If you go during the afternoon, expect to wait at least 30 minutes before you talk to anyone. When you finally do get service, it will be from someone who is unhappy to help you and unwilling to fix any problems that may arise during the billing process. For example, I keep having the same problems with a particular refill--it eventually gets remedied-- but when I try to have the same prescription refilled again, it causes the same problem and the same hassle. Why can't they learn from their mistakes? I'm taking my prescription elsewhere because I do not have time to make four trips for one refill.
