Products that don't last to their BB Date

I have sent an email with regards to milk that was purchased 3 times in a row and all 3 times the next day it was sour.

I have phoned left a message and yet no one comes back to you.

Good day

I have been using C***** products since I can remember.

I had to since Saturday replace my 2l everyday and then I have not finished it yet because it is sour.

I bought a 2l on Saturday, Sunday morning it was off bought new one on Sunday had to replace it yesterday.

I bought it at the supermarket close to home.
