No one should ever be asking you for admin access unless you are hiring a reputable web site designer. The theme we purchased did not work. We sent several screen shots and videos showing them their documentation does not match the actual theme which sure enough resulted in them asking for wordpress admin access. Hard pass. Go to a more reputable site like Theme Forest.
Which is basically the themes SKT is ripping off anyway. Just go straight to the source where you will have a chance to get your money back. Very clear that all these 5 star reviews are fake.
