The Menzies Distribution website
gives contact details for this branch as Phone: 0845 200 7683, Fax: 020 7536 864005. Unhelpfully, this fax number is incorrect as it is one digit too long.
The email address for this office is Bow.administration@menziesdistribution.com and a Google of it leads to
this page which gives telephone number 020 7537 3282.
Please let us know how you get on. If this is a suitable alternative I will add it to the database for others to use.
