Attack not automatically recalled

Everyone I've talked to agrees that if two players attack the oasis, and one of them occupies it when they other's troops haven't arrived yet, the second player's troops should be automatically recalled, because the oasis has a new owner. I sent this letter to support:

" Hi,

I just attacked the crop oasis at 129:383, the attack took 15 minutes to arrive and when I got there I noticed Hlb had already took the oasis.  I used two coins to callback when the attack should have automatically been recalled due to the oasis having a new owner.  Please can I have my two coins back.  
Thanks,

1Zero2"

And this is the answer I got:

"Dear Player

it will always cost you when you recall your troops

this because Hlb attacked this oasia before you

Thank you for your cooperation and support.

Regards, 
Iori"

As you can see, the answer isn't really about my question and I don't feel like arguing with someone who's first language isn't English. I've done this before with other support and never got anywhere. All that's happened is they've complicated the issue more by saying things like I should raise a new issue every time instead of pressing "Reply" on their answer, or what's my email address etc. So I came here. Hopefully I can get a decent answer and my two coins back, seeing as they should never have been spent

Hi,
we've checked the log:
2 coins; Date: 2012-02-28 16:04:33; Call Back war troop
Please kindly note that if your troops had already arrived there a withdrawal would have costed 5 coins instead of 2 coins listed here. Therefore, the situation was not what you've mentioned as "when I got there I noticed Hlb had already took the oasis"; instead, you'd spent 2 coins to callback your troops before they arrived at that oasis.
The status of that particular oasis was unoccupied when you sent your troops to attack that oasis; the ownership of the oasis had changed during the marching, if your troops kept marching there, when they arrived at the oasis, our system would judge whether the ownership has changed, that is to say in your case, if you hadn't callbacked your troops by yourself, when they arrived, our system would automatically recall them for you.
In all, your problem was not a system mistake and your coins were consumed to callback your troops.
If you have any other question please feel free to contact.

So it's my fault and I should have waited a few more seconds and spent an extra three coins? All the other times I've been in a similar situation, my troops have been recalled as soon as ownership changed. But thanks for your prompt answer....

If you waited for a few more seconds, the troops will be automatically recalled by system.

It's a shame about my coins but oh well. Thank you for your clarification, both of you. Back to playing then

I do hate to be rude... but support doesn't always seem to answer anything. And I mean this in game. I have to come on here and scope out an answer on the forums.

- Don't take this personally, just what ive noticed.

with so many glitches... We need support that undetstand us and can help! Iori is incompitent and needs to be dropped!
