At first, they charged me $15, then an additional $50 for a standard unlock, and now they’re billing me $317. I think it’s wiser to invest in an unlocked iPhone; these continuous charges seem suspicious. Be cautious; this could be a scam. I’ve already requested a refund from my bank because I’m concerned they won’t refund me, “If I had known that the premium cost would be this high, I wouldn’t have chosen to work with this company.”
