Claimed to be a debt collection service. The voicemail said any info they obtained would be used for that purpose. I had no debts, needless to say, they got no info.

Very suspicious.  Left a voice mail for me to call back.  Claimed to be a debt collection company and asked me to give her my birthday otherwise, they won't be able to give more information.   I refuse to give out any info as i don't recall I owe any debts.

Trans World Systems. Calls several times a week. Always leaves the same generic message that they are calling trying to collect a debt. In Maryland they also have several local numbers that tell you to call this toll-free number: 443.552.5819 / 443.552.5884 / 443.552.5895.

According to the website, they are a medical debt collection agency, but they never leave any information about what medical provider they are calling about.
