updating blood sugar usage on machines

I keep getting calls from this number! When I answer, someone is there for a split second, and then I am disconnected. When I call it back, there is a auto attendant that says all of our agents are assisting other customers, please stay on the line until the next available agent can assist you, the music starts and then I am disconnected. I have been getting these calls frequently over the past few days and it is very annoying!!!! Yesterday they tried calling 4-5 times. I have started not answering these calls and they are still coming in. Please make them stop!!!!

Called at 4:25pm today. I said, "Hello" twice before being disconnected. Called back right away, the line didn't even ring, to an Indian male recorded voice telling me all representatives (to what?) were helping other customers and to call them back. I was then disconnected again.

Wasn't home at the time of the call approximately 1:30, didn't leave a message so must be spam

Got a call from this number and it as a foreigner I could NOT understanding going on something about my pain medications. After I stated I could NOT understand her she said something like "You are not listening" I hung up on her then.
