Who called from 9513737713

sorry :( that's not cool for someone to say that

They get hostile when they know you're not falling for their spiel and often resort to profanity and vulgar language. What do you expect from people who have to rely on people answering their phones to make them money and provide ways to steal?

no answer

I've been getting calls from this number but they never leave a message.

Calls sometimes 5 times a day, never leaves a message and always busy
