Received a call, picked up and got a blank line.  Have no idea who they are.

Basically I picked up and hung up on them. Caller ID says Great Southern, which I do not recognize. I am on the Federal DNC so they have no legitimate reason to be calling me - therefore this is a scam.

keep receiving unwanted and unsolicited calls from 321-248-2261 / no message

Calls everyday without saying anything.

Receiving up to 5 calls a day from this group. Number always comes up as Great Southern. Number traces to Apopka FL. You can tell it is an auto dialer and there is no one there to answer. If you call the number back you get the message "leave your name and number and we will get back to you" and "if you wish to have your number removed from our phone list leave your name and number and we will remove it". They don't. They also don't stop calling. Ordinarily telemarketers will call you once or twice a day for a few weeks then stop. This group has been calling non stop for three weeks up to 5-6 times a day. Reported them to the FTC Do Not Call list not that it will help as most of these companies never check with the Do Not Call Registry. Verizon will not block the  call so you are left to deal with these vile folks. A pox on all telemarketers! LOL At least you get to develop patience.

Calls several times a week, several times a day. No one there when you pick up. Tried to trace it back but without luck. Hope someone else can figure out who this is so they can be stopped. Number comes up as Great Southern which is listed as a General Contractor in Apopka, FL but which is listed at a different number. Tried tracing that company but little information available on it.

Calls on cellular phone and hangs up.

calls several times a week, sometimes shows name as 301, or Great Southern, also number changes to 352-364-5978
