same thing here.. keep getting called by ADSPLUS and they don't leave a message. we are also on the Do Not Call Registry. I keep reporting callers but we keep receiving these types of calls.
I have received multiple calls from "ADSPLUS" ... I have answered; no one is there. I have tried to call back; either no one is available to answer your call OR this mailbox is full, please try again later. I'm sick of it !!!! They don't leave a message either. The number on my CID is 832-0352. This has been going on for months.
