Spoilt Milk - C*****

Good Morning, every week I purchase 6 x 2lt C***** milk, in September last year, I had a problem with milk getting spoilt before the expiry date, I contacted C***** via telephonic and email, all details regarding my issue was emailed to them there was no response till this day regarding my previous complaint, Today again I am experiencing the same problem, The expiry date on the milk is 10 Jan 2021 yesterday was the 6th and my milk is spoilt:( Im not going to take the time complaining to C***** as they do not take it serious and are not helpful in resolving this matter. Irrespective of this product been so expensive we support C***** and this is the treatment we get. The cheaper milk seems to last longer than this expensive product.
