westlake financial horrible customer service, unreasonable Los Angeles Nationwide

Westlake financial is terrible, I've had multiple issues with them. Everything from lack of empathy to straight up rudeness. They have changed my due date for my loan permanently when I was told it was a one month change then they refused to change it back stating the reason that when they changed it, it put me one month behind on my payments. I've been experiancing problems with my vehicle for the past year, its been overheating. Sice this has started I've taken it into multiple mechanics and have spent a thousand dollars trying to get this issue corrected. The finance company (only in the ladt week) told me that I could email in a copy of the recipt from the shop and they woukd push a payment back for me. I did and they did. Turns out, replacing the heater hose and heater head wasnt the issue, so it was another 200.00 worth of work that didnt help. That on top of replacing the thermostat housing, thermostat, water pump, timing belt, radiator and multiple hoses hasnt fixed the issue but sure has run up my bill. I called into westlake financial today finally fed up with the car, asking them to dwlay the next three payments or until I could figure out whats causing the issue and get it fixed (if that happens sooner) because I couldnt afford to keep dumping money into my vehicle as well as paying my 300.00 a month car payment. The first time I spoke to someone, she disconnected the call, claiming that she was teansferring me. The second time, when I told the woman my issue and what I was going through and that I no longer wanted to pay 300 a month for a car I couldnt drive  she was very rude,  she flat out told me no because of the delayed payment I had already gotte. For attempting to fix the immobile mess of a vehicle. Again this woman was an emotional 2x4, no attempt at empathy or connecting with the customer. I told her that in that case I will not be paying the car payment or attempting any more repairs on the vehicle. Her retort was "well, you know thats going to affect your credit right?" My response to the scare tactic she was attempting was less than professional.  the conversation ended with her submitting a voluntary surrender request but informing me that it most likely wont get approved because the car isnt currently running, and westlake doesnt take broken down vehicles. "Well neither do I" was my response.  I have delt with westlake for 3 years and every time I have called them its been a terrible hassle,  even to just pay my bill, when I thought they were doing something good for me it always turned around to bite me in the butt. I suggest everyone stay away.
