Coca Cola - Flat

On 30 December 2015 we bought a 2l Coca Cola from the above Pick 'n Pay. We were on our way to our holiday destination (we stay in Sedgefield) upon arriving there and wanting to drink the coca cola it was flat, the seal was not broken but the contents was flat.<br> <br> We shop at this Pick 'n pay all the time and regret the fact that it was turned into a pick 'n pay, when it was a spar we never had any trouble. Now the prices are more expensive and the cooldrink is flat, we bought a white bread just a week ago and it was old not fresh at all.<br>
