Westlake Financial Services California westlake financial services they harass me about my payment arriving too late, never taking it off my balance. i am not getting credit for it. its not evern on my credit report. i sentd my payment by check it lays in their mailr los angeles, California

I am reporting Westlake Financial Services in Los Angeles CA. 90010. They call me at least 20 to 25 times before my payment has time to get in. My payment is due the 31st of every month i mail it at least one week prior to the due date. They should receive it within a week. I always mail a check for with my account number on it but they say that they don't receive it. It was after I mailed my payment 2weeks later they call and threaten to reposse my car if i don't call them and allow them to take it from me if i don't call the bank and do an eft(electronic withdrawal). My payment stayed in their mail room over a week. I threatened to call an attorney to prove to them I made my payment and fax them a copy of the check and even give them my banks telephone number to verify., of course they didn't believe me so I ALMOST LOST MY CAR!!!! I recently tried to better myself and tried to purchase another car and use mine thru them for a trade in. I bought the car for 4995.00, I have been paying on this vehicle for a year now. The balance is not even down to 4995.00 yet. they ran my credit so I could purchase this other car and was'nt even on my credit report. You bet your sweet behind if I miss a payment it would destroy my credit. I filed bankruptcy and I purchased this car to rebuild my credit but it's not even on my credit report. I was told by another car dealership I got SCREWED  and I sure don't appreciate it at all. Today is March 5,2010 they have called me 15 times in the last 2 days my payment was mailed on February 24,2010.
