Freeradius disconnect user after hit traffic

RouterOS General
1

Hello everyone
I configure freeradius for authentication my users also work authentication fine but when my users hit the bandwidth per month (1G) those are not disconnect automatically…!!!
But if the PPPoE connection’s are disconnect other than cann’t connect.

My problem is when the customers is bandwith is hits are connections is not disconect.

I make a sqlcounter in counter.conf:

sqlcounter  poyrazwifi_Limit{
	counter-name = Mikrotik-Total-Limit
    check-name = Mikrotik-Total-Limit
    reply-name = Session-Timeout
    sqlmod-inst = sql
    key = User-Name
    reset = never
	query = "select (sum(acctinputoctets) + sum(acctoutputoctets)) from radacct where username = '%{%k}';"
}

and this Cods on site-enable/default ~ authorize

poyrazwifi_Limit{
		reject = 1
	}
	if(reject){
		ok
		reject
		update reply {
		Reply-Message := "Your account has expired, %{User-Name} your bandwidth is limited "
		}
	}

And in the radcheck mysql database:

insert into radcheck (username,attribute,op,value) values('test','Mikrotik-Total-Limit',':=','1073741824')
