Any ideas who this might be?

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!

Just annoying!

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.
