Ahh.... they've tried to refund to what they think is the change address... but I think they refunded it to themselves!
In your original transaction, you created outputs:
14A9qNNXsg9ywGFPqcku1V87pVDc5tCFcR - (Spent) 0.02612337 BTC1A4n3C7adw5dgWpbktHcMCzEC6yjvyxRzF - (Spent) 0.46608539 BTC
Now, If I'm correct, you were attempting to send 0.02612337 BTC right? and 1A4n3C7adw5dgWpbktHcMCzEC6yjvyxRzF is an address that YOU own right? (should be in your Addresses tab in Electrum or use ismine() on the console).
Well in this latest transaction... they have created these outputs:
14A9qNNXsg9ywGFPqcku1V87pVDc5tCFcR - (Spent) 0.02561027 BTC1K8ba2SpCxX7EvdRnio9swiAFHRZGTcNE4 - (Spent) 34.48766378 BTC
They sent the "same"[1] amount to the same address!!
You'll need to contact them and tell them they need to send that 0.02561027 BTC amount to either 1A4n3C7adw5dgWpbktHcMCzEC6yjvyxRzF or your original 1LKmBfnfUkRXBAVkzmjFBBUaqikoxF78Va address!
[1] actually slightly less, but I'm assuming they're converting USD to
BTC
