I too keep receiving calls from this number without them leaving a message. I answered the phone once and they say in spanish, buneos tardes. I hung up after saying hello three times. So annoying!
I've received a call from this number a few times. If I don't recognize a number I never answer it. Each time the person calling never leaves a message. I've tried calling the number back but it doesn't go through like a normal number should. Every time I try to call the number before I can even finish dialing the full number I always get "We're sorry but your call can not be completed as dialed....". WTF is this BS!!??
Today I have gotten THREE calls from this number 210-198-4422 in THIRTY MINUTES. These calls were in the morning 9:15 to 9:45. My caller ID shows this caller as "Unavailable". The first call I answered and said "Hello" twice and they hung up. The second call I just picked up the phone and hung it up. The third call I informed them that this was the third time they have called me and that I do no accept unidentified calls and I will be reporting them if they call me again. I did not get to finish my statement before they hung up. I am on the Do Not Call Registry and have checked to make sure my registered phone number has not expired. I question how effect the Do Not Call Registry is and wonder if I would get less calls if I wasn't on it !! I have started taking another way of eliminating these calls, unfortunately, it only addresses one call at a time. I have a notebook where I have recorded the time, phone number and other info I can locate on these calls and have gone to my phone provider to put a block on these calls. It's crazy that I have to spend my work time addressing these issues. I have found if I do not answer the phone "they" will continue to call until the phone is answered. I had one number that called me 5 times in one day before I answered it. I have better things to do than answer these calls.
