Calls and never leaves a message.

its the American Red Cross. Looking to get you to donate blood.

It's the Red Cross calling about contributing to their blood drive.  Which is fine, except when you ask them to PLEASE stop calling - they do not.  And they will call...and call and call.  Luckily I'm able to block their number.

In addition to not leaving a message, the super-annoying thing is that they always call right back immediately if you don't answer the first time. The last time they called I explained that my doctor told me to hold off on donating blood due to a serious medical issue I was having, and that I would resume donating if/when he cleared me. The girl got really pushy & wanted to know when that would be... Really??? How would I know when I'm going to get better?? And instead of hassling me, how about "I'm sorry you're dealing with a serious medical issue"? It really turned me off to the Red Cross...

American Red Cross.  They call and call and call.  And if you do agree to donate blood, they are very pushy about making an appointment over the phone.  I would rather go when I have time than make an appointment I'm likely to forget.  Anyway, they stopped calling when I told them I was pregnant, but wanted to know the due date and started calling again 2 months after my due date.  Like I really have time to donate blood while taking care of a 2 month old!!!
