Would a subject access request include internal emails & telephone recording?

[ExDonut]

I complained to a large organisation (think akin to an energy provider with likely proper data management rules / teams etc).

They only responded to part of my complaint with a "go away" in more polite terms. They didn't respond to my accusation of staff dishonesty during telephone calls which may have been recorded (they refused to answer to my complaint request to preserve any recording).

If I submit a subject access request for myself/my complaint do I have any chance of getting them?
Or might I get access to internal emails between their staff about how to deal with my complaint (I'm fairly sure there would have been a "argh did you really tell the customer that, Bob?!" moment but 99% likely to have been verbal).

Thoughts, advice?

Not that it is relevant to the actual OP, but you don't need to give a reason for an FOI either. Nor prove who you are.

So much rubbish on this thread. I hope you can pick out the real bits. The ICO has quite easy to read guides if you want to check. But yes emails are in.

To be sure you can specify in your SAR that you want it to include any emails, internal or external where you are mentioned or alluded to

If it becomes excessive they may extend the response time to 3 months

Echo what others have said about redaction, if for example they have a list of all customers on X plan for example, all the others details will be redacted bar yours

Said company will deal with 'the dishonesty' should they choose to internally. I'm guessing the reason you are feeling like you are being robbed off is probably because you are being fobbed off.
Usually an apology is all they offer & if you aren't accepting this what do you actually want them to do?!

Hello! Op here.

I want them to fix the process the next time a customer has a similar situation. It is an everyday event and not unusual.

Think akin to buying a warranty and something being included in it. Like white goods. You phone up, the call rep tells you it's not included. Because the writing didn't specifically state washing machine.

Except the service (warranty) is on a much more important thing, something emotional like a funeral plan etc. and you were the person trying to arrange the funeral.

I don't hold out any hope for an apology but I'd like evidence they said stuff during calls so that I can take it to the industry body they're part of for formal logging or investigation/reprimand, mainly because I don't want other families facing the same response.

Thanks all, hugely helpful and grateful to you for responding to the questions I asked!!
