Defective Product and Even Worse Customer Relations

I bought a box of Pampers nappies which were all defective. The nappies tore apart when I tried to use them - every single on in the pack.

I sent a complaint to Proctor & Gamble and their response was to not refund me fully. In their own words: "We do not offer refunds" - so now I am the one that has to pay for their defective product.
