Waiting for change of address since Feb, plus statements and IT3 for prov tax

Since February i have been asking for a change of address as the current address is no longer in use. Despite having received an email saying my request is receiving attention, NO change of address and statements are not being received. Emails have been sent in March - Aug requesting a change of address as well as statements for this period. I have also phoned in as well.

I have also asked for an IT3 for provisional tax which has to be submitted by Friday, and still no success. PLEASE can someone assist as this is now beyond a joke. Thank you
