something went wrong with merchant and i lost over 750 divines

i had a wand worth 1500 divines. i put it on the market i accidentaly hit ok and i was oh dam i still had the open window before it locks. i changed it to 1500 divine and someone bought them right after i changed it to divine and he bought then with exalteds. and when i moaned in chat i was told i was at fault. I just put feather boots on the market and i saw the price was still set to 1500 divine so i am furious .. thanks for this .. it wasnt my fault.
