EC excluding OC member’s participation in AGM

Despite a previous arrangement for the Strata Manager/EC Member to phone an OC member to include in an AGM, they simply declined to phone him, giving a lame excuse of ‘too busy…’ ( What !? No one knows how to hold a phone ? ) Subsequent written requests for information simply result in abusive emails and basically told to ‘Piss Off !!’ This results in the OC member refraining from involvement in meetings or requesting information. Is this something the Office of Fair Trading is interested in in any way ?

Please advise.
