I wrote a review on sosasta earlier and I shared this link with sosasta, hoping at least now they will react.
They did ! they immediately replied back, that they will help me. I replied to remove my number once again!!
I got a confirmation that I have been removed from the list. (mail attached). Guess what? they lied... I got my usual spam messages! The only way I see myself of their list is if there business fails completely and they shut shop! otherwise, no one dares gets off sosasta list! lol. At least now I know that the entire team is useless and I can laugh at it now!
