Googled the number - said to be NHS South Norfolk CCG related to optical health. Recently had eyes tested and wondered if it's one of those "how did we do" type calls.

Twice now about the same time (before 10am ) this call comes through. UNKNOWN. Never leaves a message or sends a text so can only assume its marketing or spam?
