I keep getting calls from bill collectors for someone who had my cell number before. I have spoken to the bill collectors and have told them I do not know the person they are looking for and requested them to stop calling my cell. Is there an app to download to block these bill collectors from calling my cell number? I have tried BLACK LIST & MR NUMBER, but neither work because when they call now, it is an answering service that leaves a message and it says, please hold the line and one of our representatives will be with you shortly, and unless I answer the phone, no one ever comes on the line. There must be an app that will block the automated messages. I only wish there was somewhere you could report the bill collectors for harassment! If anyone knows please help! I pay my bills and do not appreciate being harassed for someone who doesn't! I am seriously thinking of changing my cell phone number, but I wonder if it will happen again with the next cell number I am given. This is very very frustrating, but if anyone has an "app" idea, I would really appreciate it! Or possibly can I block them somehow from leaving me a message on my phone now??
