GM Financial General Motors Financial They repossesses my car even though I made their required payment! FT Worth Texas

I am a senior who lost my job due the covid virus pandemic, and I got behind on my car payment.  I called GM Financial to see what help they could offer, and they were very nice and allowed a forebearance plan of 3 months.  But after three months, I still could not find a job, and so had to make another forebearance plan, which I did.  They requested that I make a payment to bring the account up to only 3 months behind, which I did in August, 2020.  However, on the Sunday morning of August 30, 2020, a repo man rang my doorbell to repossess my car anyway. 

I view this as a breach of the agreement we made.  So he took my car, leaving me no way to take my wife to her cancer treatments, or go get her medication.  GM Financial says that they really do not want the car, but apparently they just don't want me to have the car.
