Scam alert. You get a call from a "process server" who then gives you this number to call with a "case number". You call and they state its a "law office". They will try to scare and intimidate you with personal public information to make you think you "forgot" about an old debt and will settle with a credit card payment within 2 hours. Don't engage. They are not a "law office". And tt's totally illegal what they are doing.
