I have started hanging up FIRST, the second they say the word warranty or ask about my vehicle, I just hang up first, that's what they are going to do to you the minute you say no.
The reason a large portion of the people are having trouble with this number is because this number is being "Spoofed" by Delta Outsource Group, a collection agency located in O'Fallon, MO. They will try and gather enough information to create an account. Many bank accounts have been drained by this establishment and many "Spoofed" phone numbers have been fraudulently used to aquire information.
This not only hurts people by the harrassment, but also hurts the establishment that the number belongs to.
Note: Insight Services is affiliated with Delta Outsource Group.
This call has a prefix on my caller id as: 11 then this phone number. ID says :Name Not Found Perhaps they are telemarketing from outside the states to use the 11 prefix before the entire number.
