Multiple calls from 08443729672 to my home and the Caller immediately requests my personal details sighting "Data Protection" and I point out if they adhered to Data Protection Legislation they would accordingly advise of the purpose of the call and verify that they are authorised representives of the organisation they purport to represent. Caller fails to provide any information except a name (Aon Solutions) of an organisation that I have no contractual relationship with. I refuse to provide my persosal details until an explanation of the purpose of the call is provided and following refusual the Caller becomes belligerent.
