Don't think anyone can help you on this as you cannot give any information on the results of testing.
We are electricians Not magicians,
bit of a poor show not doing a full test first, during or even after so a big lesson learned on this i think.
No matter how much the client wants you to do it yesterday if not quicker and puts preasure on getting it done only means you failed to arange an appropriate time to carry out this job giving you time to do any testing required.
Perhaps you got the job because you were the cheapest, not doing out of hours. Now you know why.

2 weeks later i was told that the ALL rcbos had tripped at the same time with nobody using any appliances



Just looked into this crystal ball of mine, it tells me the information off the client is inaccurate,the rcbos didn't in fact all trip, the fault will turn out to be a run of the mill problem

di have that happen once all RCBO's tripped they were cheep one's the fault was a faulty kettle and it tripped big style no faults on any circuit other than the kettle so i carried out some RCD tests and found that the physical force of the RCBO tripping caused the rest to trip so could well be that
