how scary!
I agree with Vic, have them tow it to the nearest "authorized" dealer to repair what ails it. Yes, I would write a letter to pauls boss, that to leave a handicapped woman stranded was unacceptable behevior and you are hoping he will make it right. (perhaps you can get some free services for your trouble) As for mom not answering her cell, perhaps she was under the dryer and couldnt hear it, or perhaps she was stressed and refusing to even look at the screen to see who it was.
Please continue to see your therapist and ask for some coping skills to deal with dismissive folks. You deserved better treatment from many directions. I am glad you called 911.
