Service about a product returning

I phone Frikkie from Mosselnet on the 31 Decemer 2014 to explain to him that there was a misunderstanding between me and my husband about the watch he bought from Mosselnet for me for Christmas. It is not the correct or specific one I wanted. He told me that they are closed at that time for the festive season and I must phone back on the day they reopen which is the 12 January 2015, which I did. He said I must give a few days so that he can discuss it with Casio and explain to them what happened. He also said that that specific watch my husband bought he had for a very long time in his collection and no one ever bought one like that before, so he is scared that if he takes it back he is going to sit with it again. I waited for Frikkie to phone back, but he did not. On the 5th February I send him a message telling him that I am going to send the watch via my sister that is visiting here back to George and she will arrange with him to collect it in Mosselbay. He send back and said Casio does not take the watch back. I do not think this is acceptable from such a well known company. I have heard only good things about Casio in the past, but this is unacceptable.
