I get a call everyday from this number.  No one on the other line.
Just Hangs up.  This has been going on for over six months or so.

How can I stop them.

I got a phone call today from Redline Recovery. They were asking for the people who previously had our telephone number. The mand was quite rude when I informed him he had the wrong number and insisted I was the person in fact lying and hiding. After he screamed at me that I needed to pay him or he will call back the next day and the next day and they next day. I hung up on him. Only for him to spend the next two hours calling back every five minutes and leaving rude,cursed filled messages on our answering machine. Our Phone message clearly states our family name and not the name of these people. I don't know what to do? Aside from changing my phone number. We are always getting calls for these people, but this has been the absolute worse.

Thanks for showing your level of intelligence with your post. It's people like you that allow bottom feeders like Redline Recovery to exist. FYI for you, more than half the people in America are threatened and harassed by collection agencies AFTER going through identity theft. Next time, before you shout out another of your intelligent opinions, take five minutes to do a little homework and get your facts before you choose to call someone a deadbeat.

they were not trying to defraud her they were trying to figure out why a 93 year old had a credit card and didn't pay it there are usually three reasons for this. 1 the person completely forgot they had this. 2 life  or situation prevents this from being paid of 3 fraud. and let me tell you 90% of credit card fraud is committed from someone int he family ummmmmmm yeah i know high number but its the truth so now what will you do.
