With “contact us” facilities embedded in the corporate website there is usually no other way to contact the company, they do not give the general public the facility of being able to Email straight in, you have to use the embedded contact us, which means that they are in control. Recently had cause to complain about breaches of environmental health in a large supermarkets in store cafe, only way to contact the corporate offices was via the embedded contact us, needless to say other than the automated receipt nothing from them in response and of course because of the method of contact no copy on your own computer to refer to.
