Finally arrived today together with card saying that a Customs fee is due on the original delivery which has turned up from somewhere (another £15.17 in ransom money). I've paid again so it should arrive on Saturday.
Mary said that I could dispose of the duplicate should it ever arrive so if anyone wants it and is willing to pay me £20 plus postage to help offset my Customs payments then please PM me and I will send it on.
I find it amazing that the original supplier and myself are both out of pocket but the postal services which helped cause the problem have made extra profits.
