Nursing home parent and old credit
My mother is almost 97 years old and has been in a nursing home for a year now, with multiple health issues and slowly advancing senility. During the last few years that she had somewhat confused control of her own finances (before my sister took over bank accounts, bill paying, etc.), there were several credit card companies (among other entities) who called her and used slick, high-pressure tactics which resulted in her signing up for credit cards and purchasing items on them. My sister, who has her Power of Attorney, called and wrote letters to each of these companies even before Mom went to the nursing home, explaining that she was no longer capable of making such transactions and to please cease and desist sending her things. One by one, all those companies complied and dropped charges once they had been notified - all but one: Bank of America. She had charged something relatively minor on that card (about $100), which she didn't even remember signing up for. Although my sister has called, written or e-mailed them many times and explained the situation, they have continued to tack on late fees, penalties and an assortment of other charges until the balance they are now trying to collect is nearly $7,000 (almost unbelievable, I know).
We are at wit's end. At this point they are now harassing my sister and asking her to pay it, saying they will reduce it to $1,500 if she pays it over a period of months. She is not financially able to pay this debt, nor am I - both of us have our own serious health issues - and we are the only surviving siblings.
What exactly is the nature of what this company can do to us if the debt remains unpaid, and what further action should we take?
