My first book was self-published in 2012 through iUniverse who obviously sold my phone number. Eight years later I'm still being harassed by creeps who somehow get my personal information, without them doing the research to learn I'm a traditionally published author now. This company keeps calling me and I have never given them my phone number or authorized them to contact me. The messages sound pre-recorded.
The fact that they would write a positive review about themself here and for the Better Business (and then say, "hey look at our positive reviews") is really classless. There are ethical ways to run a company and that includes not telemarketing (no ethical company on the planet does this in 2018) and not trying to mislead aspiring authors. If I had to do it over again I would only use Amazon to self-publish. They can at least be held accountable to a certain degree.
These companies promise the world but deliver nothing. All of these companies have been around for over a decade and no one (out of hundreds of thousands of self-published authors) has accomplished anything unless they have done the work on their own. Every successful self-published author I'm aware of gets the credit for getting recognized in their own way. Usually by thinking outside of the box. If you are being harassed and know other self-published authors, talk to them about actual returns on their investments. Do not trust any of these companies.
Most self-published authors fall for these scams at least once. Be the crafty one and don't. It'll save you hundreds or thousands of dollars in the end. Spend the money on self-hosting a WordPress blog and link it to Twitter. Then put in the time. It'll pay off in the long term.
I didn't like: Phone harassment, Stolen phone number, Telemarketing harassment, Pre recorded messages.
