Collections for USAA

I have been receiving theses calls for 2 weeks. They never leave messages, and it makes me super mad. Idk why they r calling me im only 13.

same here got a call alot this past week and says invalid number.........

Same here. I don't know who they represent, but they have the wrong number.

For the past two weeks I have gotten at least three calls a day from this number and have no Idea who it is. They never leave a message.
I don't answer phone numbers I don't know.
I called them back and I am put on hold for the first available representative it's important they speak with me
it is a bill collection agency
