Hello,
How do I force a telemarketer/scammer who is leaving a message on my home line voicemail that he wants to "schedule a delivery of an Emergency Medical Alert system that has been recommended for you". I've registered on https://www.donotcall.gov/default.aspx but he keeps calling. I live in California.

Hi, I not long ago applied for financing to have a new air conditioning unit and heating system installed in my condo apartment by a well known company located in the South Suburbs of the Chicago land area. I was to put 1400.00 down because that's what I could afford to do having other pressing issues and household debts to pay. The installers came to my home with the new air conditioning unit and heating system and began to take out all of my old equipment (that was still working, but old and I desired new systems). The installer soon discovered that neither of the new systems that he had would fit in the old spaces where he had already yanked out the air conditioning unit (as he put it) and also cut the wires and took apart my old heating system. When he called the company, they told him to cut the brick without my and the associations knowledge since it was not allowed to do. He did not do it, Thank God. After I chewed out the salesman and the company about their practices, the installer was told to put the old units back until they could figure something out. My heating system did not heat properly after being re-installed and of course, the air conditioner was unusable after yanking it out and cutting the wires. After contacting them via a letter from an attorney, they only wanted to give me $500.00. I only expected to pay $1,400 down and yet, ended up having to pay out an additional amount of $2,965.00 that was allotted for other household things to get new heating and air conditioning from somewhere else after nine days of being very cold in the room where the air conditioning space was just left open. The company never contacted me back until they received a letter from the attorney. They claim that the main office wasn't informed of the problem. I had to pay $4,365.00 instead of just $1,400 to get things right again. The additional $2,965 was not in my budget to be used for the project. This is why I went through financing with their company. I could not get financing with another company and as a result I have been very inconvenienced. I know there are probably no contingency attorneys that would take a case like this, but is there something I can do???

I'm in California. I owed $3000 on an Amex cc that I never paid. They sent it to collections who eventually filed a lawsuit locally. I didn't respond so they got a judgement and put a lien on my house. We're $1m underwater on the house, we're in default and we're probably going to lose it. I have three questions. 1 - Why did they put a lien on the house? Isn’t it easy for them to pull the records and see that that’s a deadend? 2 - The judgement is for $3300. I was told that if I don't show up in court the judgement is limited to $3000; interest, penalties and atty's fees cannot be added unless I appear and contest it. Why is the judgement for $3300? 3 - I have money in my business checking (sole-proprietorship) that can easily cover the $3300, so I was about to call them and negotiate a settlement, before they attach the checking account. But I was just told that because they have a lien on the house, they can't also pursue the checking account. Is that true? tx
