Developer first calls the review false accusations and the admits to the facts later. Trying to intimidate customers to give him a positive review. I suspect all the positive reviews posted in different places he mentioned above to advertise on www.remarpro.com platform are the results of this type of extortion as is demonstrated here.
There are host of other free reputable phone number companies who do not intend to extort customers or put them at risk of identity theft. I hope the Swedish and Indian authorities keeps a close loop with his company.
