There is a direct correlation between news events and call spam.
When the pandemic struck, there were many calls I started to receive for owed money (from fictitious departments… c’mon guys put some effort into it).
Now that borders have opened between countries I am getting calls for packages I have ordered waiting at the border (maybe it’s that ruler I ordered four months ago).
The point is, if your business is entirely driven by reactionary events where you are waiting for something to happen to grow (not that I am encouraging the growth of call spam) you will always be at the mercy of other industries forging your path for you.
