Got a call from this number on 5-23-14 at 6:30 PM but they did not leave a message. I've gotten them before and like others,  when I call back it's a Magic Jack customer who is not available.  These robo-calls and telemarketers are worse than ever. The no-call list means absolutely NOTHING to them since no one is ever prosecuted. One pesty, obnoxious telemarketer had the nerve to tell me than no one pays any attention to that law so I had better get used to him calling my home as much as he likes! Something has got to be done about these A-holes.

I called the number back, 510-545-8047 and it says "the magic jack customer" I hung up. they call several times a day every day. I'm going to pick up the phone tomorrow and cuxx them out, so beware you idiots who are calling me!!

My fiancé and I received a call from this number.  I do not know who this is.

Annoying call from 5105458047. !!!

I received a call from this number, but they didn't have my name.  I keep receiving calls for this person, but I don't know who he is.

Robo call came at 6:30 pm on 3/21/14. Recorded voice said 'Sales..." so I hung up. Might be a scam checker for a debt collector.... ;)

Got a phone call from this number.  Guy claimed to be looking for a guy named "Larry."  When I told him he got the wrong number, he asked me if my address was something that it wasn't.  I told him again he had the wrong number and he hung up.

Just got a call from (510) 545-8047 at 6:02 pm on Tuesday, March 11, 2014. A recorded message alleged to be sorry a human call is not possible to tell me about a local fund raiser by a local organization. If I could take an axe to the equipment being used to harass people like all of us posting here I would. I called back twice. The first time I got a busy tone, the second time I was told that the 'Magic Jack customer's mailbox is full'.

After visiting this page I re-viseted the national 'do not call' registry to verify that the land line this call came to is still on their list. After I receive verification I will enter a complaint, and I hope a lot of other people do too.

On Feb. 27 and March 4 and 8, 2014, I received calls from 510-545-8047. The caller never leaves a message and when I answer they do not respond. I'm tired of telemarketers and pollsters calling so I just registered my number with the National Do Not Call Registry at http://www.ftc.gov/node/199931. You can file a compliant on the site too if telemarketers/pollsters keep calling you. Good luck :-)

Got a robo-call from (510) 545-8047 on Monday 02/24/2014 at 8:51 PM.  Part of the recorded speech was cut off.  He wanted me to call another number to donate to an organization which he didn't name.  Seems suspicious.  I added his number to the AT&T call screen list (dial *60 in case you have paid for this service.)

I will not answer the phone unless I know who is calling.  I wish the telemarketing and fundraising industries would figure this out.  If a human is not dialling the phone, do not expect a human to answer it!

Same old Stuff from Magic Jack...wants a Message left..NO WAY

Called but left no message.

I got a call from (510) 545-8047 today on 11/12/2013 at 8pm.  I had been getting weird calls all day.  One was something about a calling for a congressman.  Another was a call about reducing risk of big debt. ...  Another began with a beep as did all these calls.  I hung up.  The calls seem to have been from other numbers.  Then (510) 545-8047 called and said he was with the pole (or police) city and county of San Francisco, CA.  The call began with a beep as did all the other calls.  I was in a rush and said I would call back later.  I called (510) 545-8047 back around 10pm when I got home, and got a phone voice system announcement saying something about the Magic Jack customer you have called is not available to take your call.  My call log said (510) 545-8047 is from Alameda, CA.  I googled (510) 545-8047 and found it is an IP phone located in Oakland, CA near corner of 14th St and Broadway St.  I get a lot of weird calls in SF, CA.      

I was sleeping peacefully after tossing and turning and got a call from this number at 8:05 am. I wish I could slap the taste out of their mouth, it made me so mad.

Recieved a called again @603pm with this number but i didnt answer because i recieved this same call yesterday from this same number but they didnt leave a message.

Called early in the morning and did not leave a message.

same as other posters....call me every few days but don't leave a message. can't leave a message for them

I received a call from some man at this number. He asked for my husband and when I said he wasn't home, he refused to tell me who he was or what he wanted. Don't call me at 8:30pm and then refuse to state your reason for calling!

I keep getting calls from this number and on caller ID it shows up with different names, but always the same number.  Today they left a message stating it was regarding my business!!!  Just so annoying and they call up to 8:30pm.

Annoying, donations for several companies!  Says i donated money at one time. Dont recall this.

Some guy keeps calling my son from this number. He asks for the Yu residence. He won't stop calling with the same questions . . . may not be a scam but it's SUPER ANNOYING and they won't stop calling.

Must have some commercial angle?
