I received thios response after sending an email to Everest Cash Advance which advised that all communication was to be via mail and email and to stop contacting me at work etc.. I created the letter from the template I found on this site- which has been so helpful by the way:
Hello. I would like to take the time to explain to you your options now that you are contractually bound to Everest Cash Advance, LLC because of your $300 loan you???ve since obtained. I respect a consumer who researches the services to which he/she uses.
