Good point Ads, I have not had experience of the banks claims and counter claims, yet, but have read of the many delays they cause to buyers and others in Spain.
Sadly, Spain is currently politically ungovernable, with new elections likely in June, so very little to desire to regulate banks.
Secondly whilst the EU are trying to impose harsher regulation on banks, the banks themselves are opposing it and also I fear, our Mr Osborne is definitely not in favour of stronger regulation as our banking industry is apparently so important.
Just take a look at RBS figures to see how well they are doing for Mr UK Tax Payer.
Though I am a Brexit fan, I really do think the EU or even thecWorld needs to ensure banks are serving their customers NOT their shareholders and at the very least, as you rightly say are following laws that currently exist.
Again, I would refer anyone to read or see the film "The Big Short" to understand how corrupt the banks were early 2000s and how insignificant regulation was.
It is an eye opener that no one has learnt from. Morals are definitely a thing of the past.
Profit is good but greed is inexplicable.
