Vanguard is facing problems of its own, as an employee has complained to regulators about the firm’s inability to service shareholder accounts efficiently, according to the editor of the newsletter The Independent Adviser for Vanguard Investors.

Specifically, the employee is dissatisfied with errors and delays, and has filed complaints with the SEC, the National Association of Securities Dealers as well as the Arizona Corporation Commission.

Daniel Wiener, the newsletter’s editor, told Reuters that Vanguard has known about these problems and is putting off fixing them while trying to convince itself that the problem is non-existent. Weiner says that Vanguard customers have had a host of problems, ranging from mistakes in online accounts and statements, to lost and delayed transactions and even receiving someone else’s receipt of statement.

A Vanguard spokesman said that call volumes at the Valley Forge, Pa.-based firm have been high, and that it is working to fix any problems it might have had.
