Hi - my name is XXXXX XXXXX I'm a litigation
attorney. Thanks for your question, but I'm sorry for the predicament you've found yourself in.
As you know, if you signed the agreement with the company, then you're responsible for the debt - - even if your relatives won't live up to their end of the bargain.
As for what the company can do, it has the right to repossess the televisions from you; if you don't have them then it can go after your relatives to recover the units. The company can also sue you for the amount due under the agreement(s) and obtain a judgment against you.
If a judgment is obtained, the company can then issue wage garnishments or can issue a bank levy to freeze your bank account(s) and take those funds and apply them to the balance of the debt.
If you are willing to make an offer to settle that is reasonable, the company is likely to accept it- - especially if you're retired and don't have income that can be attached to pay judgments like the one they would obtain. So, it is very likely that you're going to have some leverage to get them to settle.
The best thing is usually to make contact and ask to set up a payment plan to retire the debt. If they want the tv's back, you're going to have to do your best to get them and turn them over, or the company is probably going to come after you harder.
