Longlife Milk

I bought PnP UHT Low Fat Milk 1 Litre x6 at Jean Crossing, Centurion on 20 and 26 August. Sent an email via the website with no response so I phones Customer Care where they logged a complaint about my 12 boxes of sour milk. I even emailed them a video of what it looked like. That is R139.89 that I had to throw away. Yesterday I got a letter in the post with a R12 voucher... R12!!!!!!!!!!! REALLY! WHAT A DISGRACE!!! Will never buy Milk from PnP again.
