On the FAQs page of the Landmark Collection website one of the questions is: Why do you not have a telephone number I can call? The response is ‘All communication is conducted in writing to avoid ambiguity. This provides both our clients and tenants with an audit trail.’
However a quick Google search of terms like Landmark Collections Number, or Landmark Collections telephone will reveal that there is indeed a telephone number available for the company. Indeed by ringing 01204 599820 you will be taken through to the Landmark Collections team.
