get calls from this with no last digit displayed

Got a missed call from this number.  Tried calling back but wouldn't go through.

when I answered this call, the recording said it was a diana regarding a carpet cleaning service, I have gotten these calls in the past which are very annoying, I already changed my cellphone number but somehow these recorded calls keep coming thru, something has to be done about this it is really annoying!

Got a call from this number a minute ago, i just ignored it since i didnt recognize the number and the last digit was missing. Wish something could be done so that these types of calls are stopped from going to cell phones.

Just recieved this call. Am surprised they allow calls like this to go through (missing a digit in the phone number).
