TDS rate change consequences

Sir,

As per Govt. notification TDS rate has been reduced by 25 percent, from 14th MAY.

But TDS deducted @ 10 percent instead of 7.5 percent under 194J and deposited in government account erroneously.

example. invoice dated 23rd May of Rs. 10000/- . Tds deducted Rs. 1000 in liew of 750. and deposited on 3rd June.

now what can be done, is there any solution available?

please guide...
