Recurring Flat Coca-Cola at a Local Athlone Shop: Concerning Quality Issues

I am a local resident of Athlone and a frequent shopper at a particular shop on Lawrence Road, very close to my home. As a huge Coca-Cola *****, I've been incredibly disappointed by a recurring issue with the Coca-Cola products purchased from this store. On two separate occasions recently, I purchased 2-liter Coca-Cola bottles from this shop, and both times the drinks were completely flat, tasting like mere glucose water with no gas whatsoever. It's possible I just picked two unlucky bottles from a larger batch, and that other bottles in their stock are fine, but for me, this was a consistent and frustrating experience. The first time, I didn't return it, thinking it might be a one-off. However, when it happened a second time on a subsequent purchase, I verbally informed the staff that there seemed to be a serious problem with their Coca-Cola stock and that they needed to investigate it. Despite my feedback, the issue clearly wasn't resolved, as I received another flat bottle. It's extremely frustrating to pay for a product and receive it in such a poor, unrefreshing state. This consistent lack of quality control for a product I frequently buy has forced me to stop purchasing Coca-Cola from this particular shop entirely, and I now get it elsewhere. I urge the management of this local shop on Lawrence Road to seriously look into the quality of their beverage stock, as this is a basic expectation for customers."
