Woodford's admin department sucks

The cars Woodford Hatfield provide are good but their admin leaves a lot to be desired. They don't send invoices unless you ask and that is a mission in itself as is almost impossible to find a human being to communicate with. Once they charged me 2000kms too much and it took weeks to find a person who could sort it out. The system is quick to send out "Noreply" messages claiming damage to a vehicle but they don't state the extent of the damage and they don't communicate any further - they just withhold funds on your credit card. Now once again it will be a mission to find an email address or phone number I can use to find out what the problem is or to get an invoice. They can really do a lot better in their admin department.
