I have been getting numerous calls daily from this number and several others. I did ask them nicely to remove me from their call list, and they hung up and started calling MORE!!! When calling back the same number, the voice mail is usually full, but twice have left warnings that I will report Mammoth Group if they do not stop calling me. They continue to call despite my being on the National Do Not Call Registry.
How do you get rid of these guys????
Suggestions, please!!!!

I received a call from this company about an hour ago. Very rude woman on the other end of the line, hung up on me when I tried to ask her questions. Tried to call back and you can only get a voice mail. I called 37 times, leaving very lengthy voice mails for them with music or whatever, lol!!!  Sent them as Urgent, lol!!! I will continue to call and bother them as they bothered me. I would suggest that everyone reading this and being harassed by these morons, keep calling them leaving voice mails that they have to take their time to listen to and we all need to report them to the federal government as it is very illegal to continue to call someone after they request to be taken off their list!!!  Keep track of your calls from them and then you can sue them after the 2th call  :)  I believe that the government gives them 48 hours to take your number off their call list.  REPORT, REPORT, REPORT OR THEY WON'T STOP!!! They now say that their name is Mammoth Group.

IDEA:  Blow a whistle in their ear when they call, not illegal if you are being harassed! I read above where they are trying to get the person's credit card numbers and DOB; this is an illegal company, be careful. Everyone needs to report them to the Attorney General, Governor and State Senator; maybe a little heat on them will get them to stop their illegal activity.

They are going by Mammoth Group at the 623-209-8628 and by Pip Web Design at the 855-811-7994; same company. Only voice mail at the 623 number but an actual person answers at the 855 number. Bomb them with calls  :)  Bother them and take their time like they are so rudely doing to us, lol!!!  If you leave a voice mail, send it as Urgent to make sure they listen to it!!!

5TH TIME THEY CALLED TODAY AND ALL THEY DO IS SIT THERE AND THEN HANG UP. FED UP!
