I get a ton of these calls every week from different numbers. One of the numbers (386-951-4173) is especially persistent. They never leave a message. I called back and they identified themselves as Vision Financial. I don't owe any money, but they don't listen to reason.
This is a sleazy debt collector dialing any and all known numbers associated with whatever account they're trying to collect on. They have called my business cellphone several times asking for someone I don't even know. I told them this is a business line, and I've only had the number since December 2012 when the line was added. They have called from several numbers in the Orange City area, each time I tell them they have the wrong number, then they use a new number to call from. This type of harassment needs to be stopped.
