Postman sharing information

[Annoydcustmr]

After advice from customers and workers really,
Yesterday there was an enforcement officer at my property (all sorted) however the postman arrived at the same time, the door had not been answered and all was caught on the Ring Doorbell, the enforcement agent was unable to clamp the car on the drive due to it displaying a blue badge, however he asked the postman if there was usually any other car parked on the property, (he didn’t introduce himself or show the postman any ID but the postman told him that yes there usually is and what car it was (there was another temporary car a few weeks prior but hasn’t been at the property atall since) this resulted in the enforcement agent nearly removing the car on the property because he believed another car was available to use,
My complaint is that surely the postman should not be able to tell people about things he knows about property’s he delivers to, whilst he may have suspected he didn’t know 100% that it was an enforcement agent for all he knew it could have been somebody casing out the property and cars in order to commit a crime,
