Company charges you an amount upfront, then claims to do some work to check the eligibility of the device for unlocking (with the carrier etc). Then they send you another email with another amount to pay, saying they did the pre-work and asking for the remainder of the payment (which they claim was advertised before and must have hid it). The funny thing is, my 2nd email came immediately, hence there’s no way they could have done any research about my line. It’s just an automated scam process of collecting money where a bot responds and tries to explain why they do this.Avoid at all costs.
