Has called about every single day and never leaves a message. Have no idea who or what they want, but they are pretty persistent. If it was important enough to call every single day then it's important enough to leave a message about who they are and what they want. I've blocked them as I'm tired of getting the calls while I'm at work.
This is SiriusXM. They've called about every other day (I'm in a 3 month free trial since I just bought my vehicle). No reason for them to call, much less every other day, and not leave a message. They always call when I am at work.
