How do refunders call companies to process refunds? Pre-paid phones and SIMs, or VOIP like Skype? I am good at refunding, and I want to start a refund service myself, but I am not sure how to go about this. I've been using a temporary number app on my real phone, but I don't feel safe doing that way. And are refunders not worried about voice being recorded? Can't they be linked that way? Or am I being overly paranoid. If anyone has answers, please let me know.
