Caller: Credit Corp

Credit Corp continually chase you for supposedly unpaid debts that they have purchased from a finance company for as little as 4c in every debt dollar you supposedly owe. So for a $1000 debt they have purchased for as little as $40.
Never ever ring them back as your credit 7 year blacklist will start again.
Your debt gets wiped after 7 years if you don't make any contact with them.
Block their number but they will continually ring you on other phone numbers that they have a rotation of hundreds of landlines & mobile phone numbers they use.
Rule of thumb is never answer any phone calls from people you don't know if they aren't in your address book.

Instant hang up when calling them back
