Phone call from this number came up as a scam caller so i didnt answer. I got a notification that a voice message was left but when i went to listen, no one had actually left a voice message and it ran through with silence.
I blocked this number and another 4 spam calls have now come through from 4 other numbers. All are continuously blocked.

They told me I won something like a voucher continue saying they weren't a scam caller... I just had to answer a few questions, I said no and they responded with ok you have a good day

No idea although it came up with a possible scam message
