Makro

So this weekend we we to makro in brakpan inside the shop that had a few specials on of the was the Pepsi MAX we bought a six pack thinking you could drink it as that's what u do normally NOT THIS TIME I have opened the Pepsi and it's off exp date is only in October it's so bad u cannot drink it so I thought ok let me then open another 2ltr bottle maybe something went wrong with it as that can happen I proceeded and opened a second bottle to no prevail it's also gone rotten. I would like for them to resolve this Pepsi problem they have as they are selling rotten food items to the public.
