This company has been told not to call us hundreds of times.They do not ever remove a phone number. I would say that the way they behave is a good indicator of how they do business. There is no way any sane person would buy anything from a company like this. SSI is even using local phone numbers to get to speak to a principal in our company.
I have had these people call, be told to not ever call, then call again 15 minutes later throughout the day.
Scammers and Spammers. People don't buy from companies that call you. Search for what you need and call yourself but avoid SSI.
