Experian Leaked Data Breach

Experian experienced a data breach this year where a number of people's personal data was leaked. They ensured all people affected (which I am one of) that we wouldn't experience any problems and they had everything under control. I now have 2 credit enquires made in November from PDG VAF2, a company I do not know and certainly did not apply for any sort of credit with, now reflecting on my credit score and has impacted negatively. I am livid and expect Experian to sort this out IMMEDIATELY.
