"Allied Interstate" calls

So now, in the past 2 weeks at least, I've gotten 3 phone messages left
by a recording from Allied Interstate, which as you will find out is a
debt collector company. I will not respond to any of these calls because
they don't say for whom or for what they're abusing the phone line
about. I have done some research about them. They're essentially a scam
operation that has tried with loads of people to get them to pay off
debts they don't owe in some way - as in they paid it off without
problems already.

So until they start saying why without the use of a recording, they're
going to be ignored.
