Airtalk Wireless review: unwanted cell phone service

A few weeks back I investigated other cell phone providers for the lifeline service I receive. Air Talk Wireless was that provider. I currently am enrolled with SafeLink/Trac phone for my lifeline/cell phone service for more than 10 years, and I wish to continue service with them. Somehow AirTalk went ahead and enrolled me without my consent or choosing to do so. SafeLink/Trac phone cut my service off over the Labor Day weekend once they were notified, I was being enrolled with AirTalk as I am only allowed 1 phone service. Fortunately, I was able to get my phone service restarted with Safe Link after a long talk with customer service. I have been calling AirTalk Wireless many times leaving messages on their customer phone line since they won't answer and also sent several emails asking and telling them I do not want their service, and I am staying with safe Link. They will not respond, only sending texts that state there shipping something to me within 7-10 days, which I also asked to please stop. If I receive anything from them, I will return to sender immediately. Can you please stop this nightmare as my phone service with SafeLink could be cut off again with AirTalk's continued ignoring my requests and demands to discontinue my enrollment. Thank you
