Insurance Annoyance

The insurance I have is good, but at the start of the New Year, they stopped doing things correctly. So I called the insurance company. They blamed the pharmacy. I changed pharmacies. Same problem. This drug store blamed Medicare. I called Medicare. They said the problem was the insurance company. These phone calls aren't fast. Hold with awful music should could as elder abuse. So I called the insurance company again. They said they sent the reimbursement the 23rd and I should be receiving it soon. I asked if they have changed their procedure and was I going to be faced with this problem in the future. She said it should be solved. It's almost April. I hope it's fixed.
