Coca Cola - Non conforming Services Rendered

Please be informed that this is now the fourth time whereby i purchased 1 x (12) Case 1.25lt mixed flavor Cold Drinks from SK Distributors - Lenasia. A few bottles have expired on the 12-08-2017, surely they are not conducting stock rotation. It is unacceptable that from date of purchase your product must be consumed within two weeks. We opened the Cokes and it was flat. This is an embarrassment to your product especially when we had guest over and had to find a bottle that conformed to quality standards. Every time you sent a representative to replace the products but what about the root cause and corrective action taken?? The unacceptable product and poor services rendered by Coca Cola to prevent this type of nonconforming service is a concern Product expired 12-08-2017 AL 2 08:25 JM

Please revert back to me.
