The call center now calling itself Integrated Services is run by a scam operation known as "29 Prime" (Russell Wallace: 9701 Jeronimo Rd, Irvine CA).... these are the turds that repeatedly call with a recorded message about getting your Website better placed on Goggle and Yahoo search engines.
Previous caller IDs associated with the number were "r2j2 & co" which is a documented 29 Prime alias.
Russell and friends sell what he calls the "prime marketing platform", which is the system being used by many of these illegal telemarketers..... listen carefully, they all sound pretty much the same... even the voices are the same. A lot of the annoying, repeated calls are coming from the same set of call centers (boiler rooms), operated or powered by Russell Wallace and 29Prime.
Not a whole lot you can do to stop these assholes.... you can try blocking their calls, but then they start using spoofed telephone numbers to get around the block list.
Best method to shut them up..... REPEATEDLY call their toll free telephone numbers and leave the line open until it disconnects. If everyone did this, over and over, and over again.... the cost of the toll free telephone charges might eventually bankrupt the assholes.
Some scam operator numbers to call: 800-491-5611; 888-513-7746
