Called twice in 5 minutes and 4 times within the last week. They have never left a message and I can't find much information online relating to this number. Will update if I do.
They tend to call a lot and there's always silence on the other end.
The call usually only lasts for a couple of seconds then the other side hangs up.
Can't call it back either.
It happens probably a couple of times every month and sometimes with different numbers.
I'm pretty sure it's just spam.
