BA communication problems

BA056 supposed to depart 17 September 2019 was delayed for over 24 hours. we had passenger on this flight & the delay is not the problem the problem is the NON communication by BA.. we tried to contact BA on internet ,their website [which is very unfriendly] & by terlephone, something we NEVER achieved . IN desperation we tried ACSA ORT on landline only to hold for over 10 minutes & when we did get through the operastor said I'll put you through to BA & once again the phone was NOT answered..[10minutes?]. we had NOT 1 word from BA the entire time even until the passenger actually boarded the aircraft some 26 hours later. This is total non communication & should be investigated.
