absolutely poor service from this company

Bought a 850g of parmalat gouda cheese, which was tasteless, I called the call Centre to advise of my experience and was told they would respond within 72 hours, no response. I called back to ask again what they are doing about the cheese. i was told because the sample left over was too small, they would not collect it nor correspond to me. So basically, its fine for they to sell a defective product and not take responsibility for this and as a consumer we should just accept this. Note that i have not requested a refund nor a replacement all i asked is what do they do in a situation where the product is defective and i kept a sample so they could taste for themselves, but they chose to ignore me hence my writing to hello peter.
