My question involves a consumer law issue in the State of: Illinois and florida. I am Illinois, online provider is florida.
I visited an only trading services provider, took part in a free webinar and concluded his services were not for me. I was contacted by their sales and I responded I wasnt interested. I was then contacted again where I explained that after doing my own research I had discovered that there were too many negative complaints against the proprietor, and I wasnt interested.
Shortly afterwards I received a barrage of offensive, argumentative and threatening emails over the course of three days. Eventually I stopped responding to him asking him to cease, and it went quiet. After three weeks or so this Friday, the same proprietor has started again sending me offensive, threatening and bullying emails. When I mentioned I was seeking legal help, he then told me he would sue me for as much as possible for defamation. I am not a US citizen and have no experience of this in this country. A lawyer I spoke to today has mentioned reporting the business to the BBB, and he mentioned contacting the Florida DA as a starting point. I have done this, but from the threats, I am wondering if I can do anything to stop the harassment for good?
Thanks for any advice.
