It suck's if you sponsor, the person that should be helping you on your way doesn’t reply to you. However with SFI you can reach out via the forums and you will receive plenty of help. As per your sponsor, if he/she doesn’t want to help you, just give them a poor review every month and send them a message saying you will be forced to do this if they don’t start helping out. Just remember it was the holiday season for many and they may have just been busy with family, so don’t be to hast.
