I'm am passed irritated, whoever is calling my phone unknown, and won't allow me to leave a message needs to stop. This is so frustrating every single day i get a new call from theses numbers 435-238-7764, 1888-509-4851, 1440-3314613, and 1253-666-7652. Tmobile needs to find out what in the world is goin on , because it's happenning with there service i'm am so tired of getting these calls.

I have been getting the same number calling me, I  just called back # 435-238-7764. It was all automated and just says "you have reached customer service, to remove your phone number from our call list press 1 now." So I did. Let's see if it works. Hope this helps.

I received a call on my cell phone (no landline) and haven't been able to determine if this is PR or not.  Usually, if it's a legitimate call, a message is left on VM.  I am blocking it anyway.  As far as blocking tools, I use SmrtGuard which has an unlimited numbers to block.  I have a BB so I don't know if they have other versions.  But, with BB, becoming abandoned because the Android & iPhone have so many other apps to use.  I'm just not switching right now since I'm unemployed and won't upgrade to an Android phone now.

As far as landline blocking is concerned, I bought a device years ago from Qwest for computer blocking using a landline (which you need for DSL or dial-up), it had an unlimited number of calls you could block.  It was like a little modem.  From what I've seen, if you have a landline, you can find a number of solutions online that is just software based.  But, if t he caller is using spoofing to make the call, you won't have anyway to block the real number.

After 8 missed calls, no messages left, from 435-238-7764, I was finally available when they called. It's a solicitor. They were trying to get me to extend my local newspaper subscription.

I picked up the phone and got the following message "this is a verification" and then left a number which I didn't have a chance to write down - that was it. I found this phone number of who called by dialing *69.
