No communication and absolute disregard for customers

If I could give less stars I would. After having one payment missed due to many factors they tried deducting bigger and bigger amounts with every try. My 175 payment has now reached 900. I have tried communicating with them to make arrangements I was rep**** by one email and then blatantly ignored. This one a contract not all details were disclosed to me in the first place. I see I have been already contacted by debt collectors. This is unacceptable as I tried to communicate an option and they didn't even care to reply on it.
