anybody able to book PEO appointments

Hello all,
Have anybody tried booking PEO for T1(G) recently .i have been trying past week and this week too,with no luck yet .
Monday got some appointments .i filled asap all the details but says no longer available. Day time i tried several times but never found one.
has anyone faced this. these days they are releasing appmnts randomly.
i saw some between 12-2,but they just vanish in 1 or 2 mins. looks like everybody are rescheduling only.
mostly i get the messages as technical problem or the 5 times in 15min .then you have to wait till the cap goes off. then no appointments are available afterwards.

If anybody can let me know , what time you have found one,it would be helpful.please it's urgent i need to book for me +2 dependants . visa expiring on end of april.

I have been trying for the past week too, with no luck. I would like to hear if anyone has succeeded in the last week, at what time is best for us to try.
Personally i have tried from Mignight to 2am, from 5:00am- 7am, randomly during the day, but still unlucky

it was just sheer luck that i managed to found one slot at belfast .
yesterday around 10am i managed to get just one slot and booked it and got an confirmation from UKBA too.looks like somebody cancelled it.
definitely booking beween t 12-2 in the midnite is a challenge.even though u r able to see the slots but they just go off in seconds.
keep trying and gud luck .
