Tim Hortons review: reward program

I buy medium Americano double double, and this is how I get my Tim rewards after buying 7 Americano and completed my reward requirements I ask for my free one as. Was told that I couldn't get Americano only regular coffee and that don't work for me as I only drink Americano so the Tim rewards does not work for people like me. Which I don't think it's fair as I have no problem at McDonald's with the same reward platform. email [protected]@icloud.com [protected]
