Do you have an accountant and/or have you been represented by a profesional adviser through the process ?
Have you considered fee protection insurance ? (if you don't already have it, it won't cover you this time but is recommended)
Who provided the personal bank information to HMRC ? They are not normally entitled to this under an enquiry into your business.
I would suggest telephoning them and asking for a timscale for closure and an indication of the likely outcome.
If you are not already represented, I would recommend a CTA (Chartered Tax Adviser) helps you to sort this out.
