Several calls to XXXX XXXX XXXX for windows installation and received a call from XXXX XXXX as the sales rep that was to come to my home. My husband was out for several open appointment times, so I opted in to visit with him alone. The measurements were done and the approval process was implemented over the phone to Service Finance and I was told that I was approved. 
I tried several times to reach MrXXXX XXXX or anyone in the Home Improvement dept. about the rewards points that I was due to receive that were not showing up in my account for approximately 4-6 months. There were several transfers and messages left, but no one would call me back. I am not sure the salesman was still with XXXX, but I never heard anything else from the salesman from any of the voice messages that I left on his phone. 
The contract amount had bothered me for some time because of the interest that was due to be paid ( which  actually amounts to double the amount financed ). I reached out to XXXX XXXX advisor, and he said that my best bet was to pay more per month. That was a good plan in the beginning because my husband ( even though we were both retired ... 6 years for him and five years for me ), was working another job. Three months after the installation, he had a couple of XXXX and ended up in the hospital ( XX/XX/XXXX ). He went to light duty for a short period of time in XXXX, but was XXXX challenged to do the work as a XXXX He is NOT on the contract. But his income was what I would depend on to do extra amounts. 
I received documents from the bankruptcy court concerning XXXX XXXX, and reviewed the information that was submitted on the initial application as well as another look at the contract. 
I returned the documents to the Prime Clerk with a note about the application and what I felt was misrepresented on XX/XX/XXXX ( a year ago ). The payments were paid on time, but without even the regular income that we had ... let alone the {$10000.00} that I was supposed to be getting per month on my own as stated in the application. Also, not having been retired for the 10 years that the application claimed. Yes, I did sign the contract but I did not realize that I had been misled at the time. Being taken advantage of should not be such an easy thing when people have to live later ... getting a commission from a sale shouldn't be ripping a person apart to get it. 
I missed the XXXX payment and since it's gone past the 31 day time frame, I'm told that a lien will be processed. I am already struggling paying the mortgage, and haven't been able to get the equity done due to the overwhelming amount of credit card debt that has mounted the last couple of years. 
The credit report ( XXXX ) starts out with Service Finance at {$15000.00} for XXXX, XXXX. ( {$15000.00} was the amount financed ... not sure how you get charged interest BEFORE the initial payment? ) After almost two years, the current amount is {$14000.00} ... and the financing is {$14000.00} for a total sales price of {$30000.00}. What person receiving almost {$11000.00} per month does that kind of financing? 
Read your contracts because you are being scammed people! 
No forms of extensions are offered so that was not an option ... not sure how long before we have to move out of our home of 16 years ( only 13 yrs/9 mos when the application was done, but it states 15 ). 
I realize that this started with XXXX, but I am not paying XXXX ... actually, right now I am not paying anyone for the windows to be to the point. But my point is ... a better approach to accepting and processing applications would have left me with my old windows and a declined application. Service Finance does not  have the results of the credit pull as they say it is only for XXXX who was their client at the time. Not sure how to get proof that one was even done to be honest?
