HORRIBLE CUSTOMER SERVICE

I am very disappointed with your customer care service,i bought x6 1 litre full cream milk, and the BB date is the 25th of June, i used one box and then noticed that it has lumps that normally occur when the milk has gone of, i sent you emails with the attached picture of the milk and have not yet heard any response from you guys, i am bitterly disappointed because i have to throw away the rest of the bottles and have wasted a lot of money!!!, their silence on this matter makes me think that they do not care and do not mind losing me as their their customer
