Four calls from this number over the last week as well (on cell#), no messages left.  Very helpful to see these comments here -- thanks!

They call leave no message I DO NOT use my caller ID as a message center so NEVER return calls

Got a call from this number. Answered it. They asked about a member of my household "regarding a credit card acct." I said person wasn't present, could I take a message? They hung up. They've called several times. I don't answer. Very ANNOYING.

Regarding my previous post about PETCO.  The caller ID also said Utah.  It could have been an independent company calling on behalf of Petco....meaning that they might call on behalf of other companies too.  
Everyone stop being afraid to answer calls.  The lady was polite.  Just answer the call and respond.  They will stop calling you.

I answered it.  It was the PETCO company calling folks who they believe made purchases at their stores.  The caller cited a specific store in my community...giving me the address.  They wanted to do a survey of my shopping experience.  I told them that I don't have a pet and didn't shop there.  The lady was polite, said thank you. And hung up.

This number has called me 5 or 6 times an they never leave a message or any detail about who they are. I haven't picked up so far and I don't plan on it.

Now they are calling my cell phone#####

Continuous calls no messages

Good for you in not giving information!  Information has a price.

Called but left no message

Just called me..no message

Got calls twice from this number with left no messages so I google it still have no idea !
So I will not answer this

I got a call on my cell from this number  385-207-7034 and so I   just called the number back .  A womans voice stated they were SSI  , and independent research agent.

They encouraged me to participate in their survey as my voice needed to be heard....... hahahahaha

Left no messages so idk??

called id says utah and phone number.......left no message

8:30 p.m. EDT.  Caller ID said "Utah."  I answered and didn't say anything.  A female voice, which sounded live, said "Hello?"  I nevertheless hung up.  I'll block the number, since I don't know anybody in Utah and assume it's some sort of solicitation.

I answered - Called ID showed "Utah" and phone # - nobody said anything.  I hung up.

I reported this number to the Do Not Call Registry. I hope this stops them from calling me again.

My guess is it is a solicitor for the Houston Chronicle newspaper.

Caller has called twice so far. I do not reconize number so I do not picl up. They do not leave voice mail so I continue not to answer. I have no idea who this is.

Unknown caller, looked on google and saw others also had gotten this.
