Debt Collection Agency call center, looks like they route through India, buy up several numbers that at all the same except for the last two digits. Will call from a different city and state each day, never leaves a message, will call again from a number 5 digits off from the previous one on the same day as well so instead of 214-459-4570 they will call again from 214-459-4565.
Don't have relatives or friends in Dallas, so figured it to be someone phishing for info, or a debt collectors. Sucks for them though, because I don't answer blocked numbers or unknown callers. Next time leave a message!
This is a Debt Collector, not sure for who, they called my cell this morning asking for my ex, of course I told them there was nobody by that name at the number, said they'd make a note and take my number off their list.
