Hey there, I'm still on Classic Tab S and I have over $100 in positive tab. I wanted to use this to upgrade to a Samsung Galaxy S7 and get the benefits listed in the koodo shop for tab medium while keeping my $50 per month plan and my Classic Tab. is this possible? when I go to check out with the phone, it's only charging me $85 up front, but it's also asking me to agree to a $15 per month tab charge which I don't want. Any help would be sweet. Cheers!
