Well I think I am sorted. I checked on Amazon to see the status of my claim, and was delighted to see that i had the option of having an Amazon gift token to the value of the refund I am due from the seller. I use Amazon on a regular basis so this seemed like a good and easy solution for me. Amazon can now do whatever they need to regarding the seller. I want no more to do with them.
I just want to point out that it is not the fact that things went wrong which has annoyed me, it is the dreadful attitude of the seller. I cannot understand why people would act in this way, it isn't good business practice.
I can recall when I worked for an antiquarian book dealer some years ago I made a stupid error and sent completely the wrong Item.Unfortunately it happened to be to America, so it would have been more trouble to ask for it to be returned. I simply mailed the buyer, told them that I had been responsible for the whole transaction, that I had no excuse to offer other than that I had made a careless mistake. Apologized, told them to keep the one they had with our compliments, and that the correct order was now on the way to them.I had a lovely mail in return, and what's more that buyer used us again, and recommended us to friends.Anyone can make a mistake, the answer is to admit it, put it right and move on
