GMAC AUTO FINANCING knowingly lied through their teeth Internet, New Brunswick

My husband passed away in Oct of 2005.I moved to Saint John NB in 2006.I bought a 2007 Saturn Ion Quad coupe.I had my payments taken directly from my account.Well in 2009 GMAC housing corp bought the apt building I was living in.I couldn't find an apartment in the city that would allow me to keep my dog.I decided to move back to my house in September of 2009.I had a lot of problems after moving back.I had to get power back into my home.That took a week to do so.I had to return to work which is a 45 min drive from where i live.Then my dog got sick with parvo and died,subsequentially my 2 puppies came down with the same sickness.All of this happened in Oct.I came home from work on Nov 20th and a gentleman drives into the yard and asks me if I am Mavis Fitzherbert to which I replied "yes".He informed me he was there to repo my car.He asked me if I was just getting home from work.He was very rude when I told him I wanted to see the paperwork first before I handed him my keys.I gave him the keys and he drove away.I contacted GMAC and this so called "lady" by the name ofNatalie told me I was behind in my payments and that they had tried to contact me and couldn't.They said they tried to call WALMART where I work.I work nights and they contacted the day people.Go figure!I never received a letter or a call while i lived in Saint John about the late August payment.I had no idea it didn't get taken out.She told me I should have checked my bank account.She informed me it i paid $1,290.50 They would release my car.I asked where the car was being taken and all I got was a phone number so I had to go on Canada 411 and find the dealership and address.She said I had 21 days to pay that amount.I borrowed money from my daughter and a cash store to get the money.I paid a car to take me down to pay the payment on Dec 04 of 2009.I asked where the car was because I didn't see it where it was parked on the 21st of Nov.They couldn't find it.They called Natalie up and she said I had to pay another $2,465.01 for baliff fees then I could go to Moncton another 3 hours away to get the car,They had taken it to the auction.Keep in mind i have lost 2 weeks of work because of this.Then yesterday I got a letter in the mail.The letter was dated 2 days AFTER they had already taken my car saying it was going to be repossed,but the letter didn't arrive until Dec.05,09.The letter stated that they NEVER intended to let me get my car back.That's not what they told me.They took my car so I can no longer get to work until I find something I can afford,they ruined my credit which I was trying to rebuild after my husband ruined it before he died.Is there anyone who can help me?I feel like I'm losing my mind.
