Australia Post has refused to release its customer complaints data for Western Australia as frustrated Perth residents continue to criticise the service and its delivery drivers.
The government-owned entity's Facebook page is flooded with hundreds of complaints a day ranging from stolen parcels, damaged goods and drivers not knocking when a person is home waiting for an item.
Many, including Perth woman Kelly Bell, also complained of waiting on the phone for hours to lodge an issue. 
Ms Bell said she had a $300 graduation dress stolen from her Bentley front doorstep in   February after a delivery driver left it unattended and in clear view a busy footpath three metres away.
According to Australia Post's policy, the driver is required to leave the parcel in a safe location, or leave a note for the person to collect the item from a local post office.
Despite the driver doing neither, Ms Bell was told she would not be reimbursed for her express-posted package.
"Australia Post failed in its duty of care to deliver my parcel safely, yes it was a dress, but what other parcels, containing 'more important' items are being left in 'safe places', only to be stolen," she said.
"Since the incident, I was too nervous to have anything sent to that address, so instead forwarded my mail to a friend's place.
"If Australia Post expects customers to keep using their service, they need to realise that mail often contains important and sentimental items that need to be delivered appropriately."
Residents in Ellenbrook also complained of Australia Post delivery drivers not knocking on their front door before leaving pick-up notes for residents to collect their item from a local post office.
"They're either understaffed and don't have time or are just lazy," one resident said.
"I don't know which but every time you go to the post office there is a huge line out the door of people picking stuff up."
Another angry customer, Joe from Beeliar, told WAtoday he had his son's passport left in his letterbox, despite it being labelled as registered mail, which requires a signature to be delivered.
The parcel had been opened by someone when he found it on   February 5.
"I followed up with the Bibra Lake branch and a gentleman there told me there was no tracking on that parcel and nothing they could do to track which postie," Joe said.
"I find it hard to believe, especially that it came from a WA state office."
Despite the complaints, an Australia Post spokesman said it had received "positive feedback" about its policy that required drivers to knock three times and call out before leaving a card or placing the item in a safe location.
"If there is no safe location, a notification card will be left under the front door to advise the recipient that delivery was attempted and their parcel is available to be collected from a nearby Australia Post outlet," he said.
"When there are no delivery instructions and a signature is not required and nobody is home, the delivery driver will look for a safe location to leave the parcel.
"The theft of parcels after delivery is concerning and we continue to provide delivery options that allow our customers to receive their parcels when and where it suits them, through parcel lockers, safe drop, deliveries direct to an Australia Post location, re-directions and twilight deliveries."
This week, police charged a Perth woman who brazenly stole a Valentine's Day gift from the doorstep of a Port Kennedy home.
Two months ago, two northern suburbs women dubbed the 'Christmas Grinches' were allegedly caught stealing presents from doorsteps in Wanneroo.
Australia Post, a government-owned entity, refused to provide statistics on the number of complaints it received, with a spokesman saying the company "complies with all relevant reporting requirements".
"There has been no reduction in Australia Post's performance levels," a spokesman said.  
"Our year-to-date service performance for Western Australia is above our community service obligation of 94%."
Australia Post's 2015 annual report stated the industry's ombudsman had spent an estimated $550,000 investigating complaints relating to its service in 2014-15.
