Twice Disappointed

For the second time in a matter of 2 weeks I have been purchasing Savanna 500mls at different locations with both having an outcome of being flat . Extremely flat . All that you get is a simple apology and that this wont happen again… only to find it happening again ! On the first occasion the brand just sent a simple apology… but to be facing the same problem again really is ridiculous at that being at a different store with different batch numbers . Why is the customer receiving defective products ??? At the end of the day it is not like I am receiving these items for free . I am paying for this for stuff to just go down the drain !
