Auto Loan Extension Approved, But No Confirming Fax Sent

Truck purchased new in late 2002, my father as buyer, myself as cosigner. Both on title. Financed through Chrysler. I made all payments, due on 6th, but fell behind after his death. I caught up again in a few months. Have made 10 payments since then, six on time or early, four between 1 and 8 days late. Have not gone beyond 8 days late since April '06. This month (March), I knew I would be late-I called on the 19th and requested an extension, Cust. Rep., told me it was approved. I was told to pay the $38.23 interest pymnt, (I did online that day) and to sign and FAX back the ext. paper being FAXed to me, because my account would not be credited until it was signed and recieved back by Chrysler. It was not FAXed, I have emailed Chrysler three times, once recieved the standard "Please contact Cust. Serv. to request...), no other replies. I called twice since then, have been assured that they have my FAX number, that it will be sent, that the Cust. Reps are not allowed to send, it must be "requested", and that they are "backed up", and it would be sent in 24-48 hours. It has now been four days, still no FAX sent to me, and my online account shows March pymt still due (minus the interest I payed).
I owe 13 more pymts including this one, I am worried that this is a trick, Chrysler is going to repo my truck, so I paid $200 more on it today (online) and will pay the rest due for March tomorrow.
My questions are:
Does it normally take days to FAX an extension, could they really be that backed up, and why ignore my calls and emails?
Will Chrysler repo my truck because I fell behind again (thirteen days from time of ext. request, seventeen days total) ?
Thank you for your help. Nan

i've never heard of a legitimate lender initiating reposession action when the debtor is less than 30 days late.

not to say it doesn't happen, but it should be rare.
