My father cannot make his credit card payments and when he moved in with me he gave a creditor my contact information. They keep calling what do I do?

I also do not answer my phone. Family members know our cell #s. We get calls from collectors for people who have the same last name as ours and people we've never heard of. We're not the debtors but how much do you think the collectors care? None because they just keep calling and we just keep not answering. The only ones these calls bother are our little dogs who howl at the phone!
These bottomfeeder collectors will say anything to scare you. Check out the laws for your state. If your name isn't on the credit card I doubt if you'd be responsible for one dime of it. I am thankful I've never had to be a collector because it must be the worst job on earth.

i dont answer the phones anymore . i turn off the ringer and use my home phone to call out . later will lok at the caller id and see who called and if i know that person id call them back , alot of em is unknown or block numbers so , i have cell ph and only my closest friends or families has it and nobody eles .
i feel so much better now , hate answerin the phone and its all blah blah blah , wake me or dad up , well no more !!

Thanks, I figure, Dad's 86 years old, he has't got good credit anyway, so what can they do, hurt his credit some more?
I just know I am not responsible for his bills. and don't know if they can come after me. They do have my address and phone number when We made a change of address for his mail..
Just got a phone call from a department store bill collector and I asked them not to call this number any longer. Hoping they will stop.

You may need a lawyer, but you probably are NOT responsible for this bill just because you have assumed caregiving. The creditor does not care, they just want the money, they may say whatever they think will get it. They can ruin his credit, but probably not yours, unless your name is on the account(s) in question. Possibly a consumer credit agency - a reputable one, if you can find any - could help with a debt consolidation or negotations; if the amount is huge, a bankruptcy might not even be out of the question.
