Isn’t that a breach of privacy and then a possible breach of data protection depending on what you do with their data?
Why didn’t you stop them and inform them BEFORE they stated speaking to warn them that it would be a recorded conversation and what was your agenda in recording them? A threat? Do you intend to involve a 3rd party in which case you’d need their permission otherwise open yourself up for a legal tangle?
REMEMBER, they probably now have you recorded saying MIDWAY that you’re recording them without their permission so something to be aware of.
It’s a grey area but companies worth millions with large legal teams are not something I want to waste my time and money fighting and potentially losing.

//If you get any more guff from them, Bob, just tell them it's for training and quality purposes the same way that companies do it to the public .//
Douglas, they always warn you before you’re connected that you’ll be recorded and not midway as done by the op.
