Sour milk..

<p>Good day</p> <p> </p> <p>I bought 2l full cream milk on Friday night the 21st of October. The expiry date on bottle is 27 October 2016. This morning (Sunday 23rd),the bottle was swollen and milk was sour. We have only used 1/4 of the bottle. </p> <p> </p> <p>Yes the milk was in a fridge when i bought it. </p> <p>Yes the seal wasn't broken. </p> <p>Yes i did turn it upside down before buying to check for leaks. </p> <p>Yes i have a fridge at home. </p> <p>No i didn't forget it outside near any direct sunlight. </p> <p> </p> <p>At R28 for a bottle, it's a rather expensive thing to throw away. Especially with 3/4 9f it unused. </p>
