EXCHANGE of item- new ? or what ?

so this weekend when online checking my autoship status stuff i noticed an xchange choice on a recent order for korres lip oil & korres body cr. odd because i have never seen xchange choice on hsn before. AND when i had asked previously about changing scent on a korres autoship was told they don’t allow scent change on autoships. figured it was something new so i clicked on the xchange choice for the lip oil just to see if perhaps it was allowing xchange for a diff korres lip oil. there was no other page appearing for me to put in any info or providing any info. then get an email saying ‘order has shipped’ & i now have an additional lip oil coming at zero chg. WHY? CS says-oh,this has been in effect for SOME products for 2yrs now & even tho there is no ‘different’ choice to make for an xchange hsn ‘assumes’ there was something wrong with the initial item shipped since i clicked xchange. AND WHEN I SEND BACK the supposed damaged item with their label it will charge me 7.95 to return the supposed damaged item. REALLY? Jeez,,, i didn’t need it xchanged & can send this small item with my own postage in small evelope SO I DON”T get dup chg for something i didn’t even WANT. don’t need this hassle. i assumed it was similar to qvc xchange policy/choices which is why i clicked on it in the first place. Is this new? or have i just been not noticing it before
