I have called the hospital about 4 times this afternoon 9/29/21 to check on my husband status who is medical ICU with Covid and the operator did not answer either time. Then I had my Son call from his phone and it rung for like 4 times and the phone was picked up but then it was hunged up. What in the world is going on? There's no back up operator? Smh
