Coke selling sealed half full cans

ABSOLUTELY DISGUSTED IN SERVICE AND PRODUCT!! i had an issue with a can of Schweppes Tropical sunset that was purchased. The sealed can was only half full. Coca Cola customer care was contacted by myself over a week ago. I was informed that a Rep would contact me in 2 to 3 days. Needless to say, that Rep did not contact me and i contacted Coca Cola customer care again today 22/10/18 - a week later to inform them that i am still sitting with the sealed product that the Rep supposed to contact me about. Customer care apologised and informed me that they would ensure the rep contacts me today. Well today the rep has still not contacted me, however a driver arrived to collect my can of Tropical Sunset. He replaced this with 2 cans of Coke, i informed him that i dont drink Coke and that i want the same product i am giving to him. His exact word were "i am out of stock" No apology, nothing.... I was so annoyed as the least coca cola could do was replace the product i purchased. I expressed my disgust to the driver and said i would contact call centre and inform them so. I am extremely unhappy that i did not get what i purchased replaced. A can of coke also costs less in the super market than a can of tropical sunset. The very least coca cola could have done was replace the defective product purchased. I will never ever support Coca Cola again. This matter was handled very poorly by them and very unprofessionally. Coca cola have just lost another customer.... poor poor poor.
