Telemarketing company
 

Business has been going badly lately. They advised me to turn to the services of SMS NA, but I don't know anything about it.

It is right that you do not make rash decisions without finding out everything about the company you are going to use. Regarding your company specifically, I can only say one thing, check out https://www.sms-na.reviews/ . There you can get a variety of information and on the basis of all this, you can then draw some definite conclusions for yourself. Personally, I always do this.
