Change of address not done, waiting for statements and IT3

Please can someone assist. In February I asked for a change of address and received a email from Client Interaction Services saying that this query has been forwarded on and if I do not have any success to please contact them. Subsequently emails have been sent every month up until yesterday requesting a change of address which has still not been done as well as statements from March - July as these have not been received. I also need an IT3 urgently for provisional tax. Thank you
