Its not just you! They keep calling our cell and found a land line number for family members! They have changed amounts they claim we owe twice already and say stuff like a civil suit is being filed and a warrant is being issued in our county...and that we are in contempt for failure to reply! They are ridiculous...they answer their phone "check services" or "investigations". The scary thing though is that they have name/number/and social security number...but keep trying to confirm birthdates. They also have wrong employment information...they are just PHISHING for information...these LOW life pieces of $hit!!!!!!!!!! They even ask if we intend to remedy the amount due before further action is taken -- HA yeah right...not giving them anything...not falling for this trap! If they keep calling...you should call the FTC (Federal Trade Commission to file a complaint) and also register your number on the National Do Not Call Registry.
This is not a scam. 213-291-0288 is from a debt collector. They are required to verify that the person they are speaking to is the person with the debt they are calling in regards to. If a debt is not paid, legal action including a law suit in a court of law, is a course of action the debt collector can take to collect a debt.
