Yes I know it's not AIBU really :)
Having followed the allocations threads through appeals, stresses/tears etc in the past I think this hasn't yet been said this year....
IF YOU HAVE AN OFFER OF A PLACE ACCEPT IT .
Even if your first reaction is " over my dead body" and are planning to appeal/wait list every school in the country, even maybe move house, bump of an insured ancient relative to pay fees etc.
LA allocations are only obliged to offer ONE place and they have done that. Reject it and you could end up with NO place for September and they have no obligation to find you one ( and any other places are likely to be further/less acceptable schools).
No DM sad faces because you've rejected a place and they now have no place please!
