Has there been an SMC Direct customer details leakage?

Today I received a fairly credible phishing attempt for Alliance & Leicester bank sent to me on an address I have only ever given to SMC Direct. When I reported it to SMC Direct they said there have been no other reports from anyone else and that I probably have a virus on my machine. This seems highly unlikely.

Has anyone else received spam or phishing emails on addresses they only gave to SMC Direct?
