How to change my appointment time with the contractor? SMATA Support Manager June 03, 2019 03:22 Updated If you have made an appointment with a contractor and you need to change your time or date you should call the contractor on the nominated contact details that have been provided to you in the email confirmation that was sent to you when the contractor was organised to attend the property. If you did not receive an email from SMATA with these details you should contact the nominated strata manager for your building and request the contact details from them.
