I’ve been getting multiple calls from an unknown number over the last few days. I’ve tried answering and just gotten scilence, when I speak they hang up. 
Today I had 3 miss calls, two within 5 minutes and another 30 minutes after that. I was in the middle of a university class and couldn’t answer. 
After leaving class I see I have FIVE voicemails total, so I spend money topping up my phone to listen to them. 

They’re all blank. Just silence for 40ish seconds. All five. 

So I text the number a simple “fuck off scammer” I mean, what else could it be? I thought it would just be some automated thing anyway (due to the silent voicemails). But then I got a message back. 

Turns out it was a manager probably looking for someone to cover shifts (as a side note I live far away from this store and wouldn’t work there anyway so ruining the relationship isn’t the end of the world). They weren’t happy and threatened to speak to my manager. I explained that I thought they were a scam caller. 


My question is am I the asshole for reacting that way? My sister says it’s my own fault for acting that way towards phone scammers. I think the manager should’ve sent a text or left a message saying who they were, or even just taken the hint after missing so many calls. 

AITA?
