I hate when I hear stories such as yours, particularly when someone takes advantage of an elderly person.

You need to tell your mom not to make any decisions that involve big bucks, unless she runs it by you.

Furthermore, she/you needs to file a complaint with the BBB and Seniors vs. Crime.

Tell them to sue you; they don't have a leg to stand on.

You might try the reverse. Get their sloppy work fixed, save your receipts that showed what you paid, and take them to small claims court.

They're scumbuckets and deserve whatever happens!
