Wrong ink delivered . As I always order enough ink cartridges for when I next run out and therefore like to have some colours in stock, the cartridges are never used straight away. As I result I did not realise I had received an incorrect ink cartridge within the order of other colours and the error was only recognised some weeks later. (incidentally very similar packaging of hp ink but different code). When reported to you I was told as it was longer than 3 days since the order, it could not be replaced! I have been a good customer of yours, clearly this counts for little.Think Tesco will be my future supplier...
