She is correct. RCI gets very few Wastgate weeks now so they value them higher than the pitiful, so called exchange operation at II does. PLUS RCI credits you with your DEEDED week - II is accomplice to the Wastegate approach that, for unknown reasons, you must deal with your deeded week if you talk to them BUT THEY can give II any week they want (usually worth less than your deeded week, of course) to II. And incredibly II goes along! So use RCI, get your week, red value and tell the weasels at Wastegate to go suck eggs.
Wastegate and II are two of a deceitful and owner hating kind. Avoid or minimize any contact with both if possible.
