We operate a business located on a bustling high street, our opening time 10am to 6pm Mon-Sat and unfortunately, we have encountered significant issues with the Royal Mail delivery service. Our parcels consistently arrive late, and the tracking information frequently indicates issues like "address not accessible" or "incorrectly addressed." or " Returned to sender" These persistent problems have had a detrimental impact on our business. We strongly suspect that no genuine delivery attempts are made, and it appears that your delivery personnel may not be putting in the necessary effort to ensure successful deliveries. here are some of our tracking details: YD111147852GB JY196889359GB KL520700796GB YD127647935GB also we have many non trackable services all of them are spare parts our customers waiting them Update: I had another Royal Mail tracked delivery YD127647935GB scheduled for today. Royal Mail provided inaccurate information, claiming that the address is inaccessible. Additionally, their delivery personnel submitted a fraudulent photo as evidence of the address being inaccessible. It appears that Royal Mail staff are providing false information, which is negatively affecting our business.
