EC rejected, maintenance - letter. Help!

Hi,
My EC has been rejected due to maintainance funds...the ECO has written that i had provided the statements till the 10/08/08 however i had submitted the statements till the 06/09/08 and my application date is the 08/09/08. The satements ranging from the 10/08/08 till the 06/09/08 were print outs taken from from the bank/branch and stamped/attested accordingly. Is it a possibility that the ECO has overlooked the statements and in the letter it has been mentioned that " the refusal is not on any general grounds".
Should i go for an Admin Review and how likely is it that the decision will be in my favour......also can some one let me know that how long does it take for an Appeal or an Admin Review..................

Hi Sumeet,
It is confusing what date format you are mentioning. Is it mm/dd/yy or dd/mm/yy? Could you please clarify. On any important document, I would suggest to use dd-mmm-yyyy or mmm-dd-yyyy format (e.g. 10-Nov-2008 or Nov-10-2008) or even full month name is fine.
Btw, ECO may have had the same confusion.

Hi,
The statements i have submitted are from 1st Oct 07 till the 06 Sept 08 (My application date is the 08-Sept-08), however statements till the 10-Aug-08 are originals ( i mean delivered to me in the post by the bank) and the statements from 10-Aug-08 till the 06-Sept-08 are in two parts i.e. one from the (10-Aug-08 till 03-Sept-08) and another from the (03-Sept-08 till 06Sept-08)......they are stamped and signed by the bank on a running papper..............I am still wondering as to why was my application rejected and in the refusal letter it has been stated that the refusal is not on any General grounds.......Also if u can let me know that generally how long does it take for an Admin review!!!!!
Hope the date range is clear........kindly advice
