I am extremely disappointed with the service I received from Royal Mail. They provided a delivery window for my parcel on the 6th of August between 11:23 and 14:23, but I was at home the entire time and no one came to deliver. Later, I received an email claiming they had tried to deliver, even though no attempt was made. The next day, I was told my parcel would be delivered between 11:06 and 14:06, but I still haven't received it. The staff in East London have been dishonest and unprofessional. They collect people's hard-earned money to deliver parcels but fail to do so and lie about attempted deliveries. I now avoid businesses that use Royal Mail because I know their service is unreliable. Very disappointing experience.
