I can understand a short run of problematic caps and bottles that smell really bad, but it appears to be a long running issue based on the comments and reports im finding. ive bought 6 packs of the diet coke multiple times and for about 2 months now the smell on the bottles has been getting worse each time i get them. the shops im getting them from arent responsible for these products so im not going to bring the stuff there. i will inform them, but not try an exchange or return thru them. Coca Cola really needs to fix the issue with these bottles smelling like mildew and burned plastic. this last bottle i pulled was the worst so far. i had to throw it out this time because of how bad it was this time. Simply please fix this
