If so, please provide details on how can verify if my details are in there as well.

Slightly pissed of Swede who called 1177 just last week here. Still I'm glad this happened after GDPR, this means everyone who's personal details were compromise should have plenty of legal options right now.

Check what time of day your call happened. Daytime? Then its probably not stored.

GDPR doesn't give you any legal option aside from asking your data protection authority.

Check out Art. 82, right to compensation. I would also be disappointed if this did not turn into a class action.
