Caller ID shows "NCH Corp"; asked for head of company maintenance by first & last name.  Put him through to V/M.

Damned fax number keeps calling here and no other number to call back and tell them to quit.

Certified Laboratories, pushy salesmen, and they'll feel free to "order" you some stuff whether you order it or not.

I keep getting voicemails from this number and there is no message left.  The last one consisted of someone whispering numbers and other things I couldn't make out.  What is the point of that?  I looked up the number and found several names attached to it.  They are Certified Laboratories, Advantage Systems, Lubrisystems, and Wcm Co, all of 2727 Chemsearch Blvd., Irving Texas, according to reverse lookup.

missed call-  did not answer, no voicemail left.

This tele m. keeps calling over and over and over......they need to stop I have already told them I was not interested.

those people keep calling to sell some fancy oil

Susan keeps calling from Certified Labs....she just will not take no for an answer...they are an expensive oil/lube company out of Texas...trying to sell products...our old female rep that eventually moved out of our territory was a little "too" friendly to the guys that work here.....hint-hint

Thanks for the info....only # came up o my caller ID 972-438-0211.  I recognize the CERTIFIED LABORATORIES name....they are very pushy...not a good experience with one of their former female reps....

This number comes from a company by the name of CERTIFIED LABORATORIES...they sell petroleum products....

Calls everyday. We are on National Do Not Call list.

Recieved call from this number and was hung up on when I answered!

Five calls in 7 minutes with beeps, no human answers.
I stopped answering after the 3rd call and now they left two beeping message on my Voicemail.

These people don't know how to take no for an answer, i tell them i had to lay off 30 people and they still want to try to sell me something. They tried to send me 5 cases of things for free and if i use them then they would charge me. I did not fall for that one. They try me once a month as least and try to switch sales people to act like they never talked to me before. We all have to make a living but WTF!!!

Very pushy salesman, but had he had his facts straight he would have been very convincing as far as being put right through to the owner or given his cell phone #. We are a small family business & I happen to be the owners daughter, it's a little harder to convince me that he told you to call him on my direct line!!!

Received call from this number, when I answered I got several beeps and no human responded. I hung up. Now, they are calling every 2-5 minutes with the same beeping sound and no one on the other end. Haven't answered again!

Telemarketing call from National Chemsearch, very pushy telemarketer, usually calls 3-4 times a week.
