I am so sorry that my Health Insurance switched our prescription plan from PrimeMail to Walgreens mail service. I have placed 3 orders with Walgreens since the change and have had a problem with each order. I had to threaten to contact Horizon to advise them of my problem with my first refill before I finally got someone to take care of the situation. I ordered a prescription through the automated system on March 7th. I had to place orders for 2 others with a representative because my physician had to be contacted. Those 2 were received within a week. On Wednesday, March 21st I called to question why I haven't received the first meds and was told that sometimes there's a glitch in the automated system. I was promised that this prescription would be sent via overnight mail and would be received on Friday, March 23rd. Here it is Saturday and still no medication!!! I truly wish I had the option to use a different carrier!!!
