sour milk pnp brand

I purchased a PNP brand milk on the 26 /12/2014 I proceeded to contact the customer care line, as I was holidaying in Saldanha, could not return the milk, and it sour, I phoned the 29/12/14. After holding for ages on my cell phone I finally got attended to, I was told to keep the product for ten days, I explained I'm from cape town strand on holiday, do I really need to keep the product. So off to cape town I returned with a 3 hr bus trip under the belt holding milk in one hand, struggling with my baggage to take another hr trip by train to Strand and walking home with the milk still in one hand, in all it has cost me a fortune in a call via cell phone,discomfort with milk in hand and Rachel from PnP Vredenburg trying her best to sort the matter out, I have still not been sorted out for all the trouble PNP product has caused me inclusive of my discomfort. I then contacted them again on the 22/01/15 and received this email with ref no.444239 with a promise that they have escalated my complaint to the Customer Care Management, I however did request a Head Office in Kenilworth to sort the matter out as no one seems to honestly care about us long standing customers. So pls can you help
