So one mistake equals they are not good? Then nobody is good as everybody makes mistakes. You cannot judge anybody on just one mistake. Can you explain why hundreds of multinationals still use PWC? And pay them billions for services?
As Bulgaria came up several times here I just wanted to mention that a fellow german Daytrader who fled Germany told me that he's paying the flat tax of 10% there. It should be mentioned though that Bulgaria hast no taxx allowance as far as I'm informed. btw: Traders are fleeing Germany beause since 2022 we are only allowed to offset a max. 20k losses incurred in trading futures, options or CFDs against the profits. E.g. you win 120k, lose 120k and you have to pay 26.375% in taxes on 100k - 26.375€ - despite not having earned a single cent. You have to pay 26.375% even if your losses surpass your profits. There are traders now who at the end of the year have only incurred six figure losses and who are confronted now with six figure tax demands which they are unable to pay and the revenue offices are deadly serious about that. Germany is now a traders nightmare. Only way out is to leave the country or to establish a company within which you are trading. But the latter comes at a cost and if you intend to leave the country later the revenue office will arbitrarily estimate a fictitous worht of your one man trading company and tax it. So you have to virtually ransom yourself before leaving the country.
Making a mistake is clearly not acceptable but, sure, it doesn't mean they suck. Why is PWC used by many companies? It's partly a transfer of responsibility from the service buyers; it's a stamp of recognition for the market makers; it's accelerating project developments in hard to move organizations, it's possibly quickbacks... Plenty of reasons. I did a short stint as a consultant at Deloitte in my youth. Hated it enough to quit as soon as the project I was on was completed. Basically the job wasn't to resolve an issue but to upsell other solutions.
