They left no message on my answering machine. It's the second time they called. Last time the Caller ID said "Kantar OPS"; strange that it said "Unknown Name" this time.

They called me today about 5:35pm. Caller id came up Kantar OPS. About 3 days ago I bought some goods at a clothing store. At the end of the transaction the cashier asked for my phone number which I absent-mindedly gave. DOOOH! Could be related??? Remember, you DON'T have to give it out if asked.I'll know better next time.

I keep getting phone calls (per my caller ID) from the firm "Millward Brown" but I don't answer. I figure if someone wants to tell me something bad enough they will leave a message. If they don't, I ignore them. However, I agree with others that it is really annoying! I am pretty sure I'm on the "no call registry" however, I will have to find out before I can report them.

hola

I am getting multiple calls an hour from Kantar Operations. They do not allow the phone to ring enough times to answer or go through to voicemail.

Calls coming daily --sometimes 2x daily. Annoying!How do we opt out of these calls without contacting KANTAR OPS. I am on the DO NOT CALL List too.Thx

Constantly calls and leaves no message.

Calls from 630-505-3008 at least 4 times weekly- hate it! Glad finally to know it's a telemarketer- want it to stop!

Call repeatedly. No message. Interesting to read all the posts. I have used the following technique and it has slowed down some telemarker telephone calls for awhile. I answer and immediately disconnect. By the time the computer notifies a telemarketer to pick up, they get dead air. I suppose sometimes they report that. Anyway, I'm wasting their time and since these callers get paid on completed sales, I'm making someone somewhere less successful.
