I bought a phone from Samsung and after a couple of days using it become blacklisted.
I contacted " remotefather.com". After talking to him I paid for his service with Paypal, and he connected to my computer and remotely he fixed my phone.
It was very fast and prompt. He knew what is he doing. the most important thing was, I contacted other places and I couldn't trust them. But here I was very relieved he did it perfectly.
Thank you for your service.
