Many of us don't use mail anymore, however it's still the only method when receving small parcels. I wasn't at home when the postman tried to make a delivery. This wasn't the 1st time I missed a delivery. In the past I would just make a phone call to their tel number 1605 to arrange a re-delivery. The call was directed to a human & problem solved.
However this time I encountered the dreaded message system

It kept asking for a number which I didn't have & disconnected me telling me that I had exceeded the alotted time

The system did not direct me to a live person & there was no option to talk to a live person.
I had to visit their web site to look for options. Their site lists some tel numbers, the Hotline, both the local & international numbers, unfortunately it directs you to the same message system.
So I finally called the general number & finally reached a live person. I spoke to a filipino

The important thing is that I managed to arrange a re-delivery. I had to jump through hoops just to arrange a simple thing as a re-delivery. If I didn't have access to the internet I would have to physically go to the post office & pick up the parcel. Sigh, it's really getting harder to get things done in Spore :(
The 'fun' doesn't stop here. My experience was, wasn't in when the parcel arrived, a delivery note was placed at the door. Normally, the instruction given was to go to the nearest Post Office near you, to collect the parcel, which for years I had been doing. Now, you are directed to SingPost HQ Paya Lebar, the note have a number to call, as you had mentioned, after listening to the menu, you get confused & still don't get to speak to a human nor know how & when to collect the parcel. So, I went down to SingPost HQ to collect the parcel.
Now, the 'fun' part, you queue at the parcel collection counter, when it reaches your turn, the person serving you ask you, did you call to arrange for a collection, "arrange for collection" ( you are at the PO HQ)!?. But the number you call gets you nowhere, the person then tell you, the parcel is with logistic ( wherever that is?), you have to wait for two hours for them to retrive the parcel. wt!?.
The number they give make you go through the hoops & you don't get ay answers, you go personally to the PO HQ, not the same day, they next working day, you can't make that call to that number, you have to wait 2 hrs for your parcel & it crosses lunch, add another hour.
In the past, it was , the parcel will go to the nearest PO near you, the next working day you go there & collect the parcel, during workig hours or call 1605 to arrange for a delivery. If you do not collect the parcel by a certai number of days, it goes to Singpost HQ, and one will have to make a trip there.
The post office is now like a convenience shop, it sells everything from candies to cookies, to insurance to phone cards, do remittances services, sell electronic goods, mobile phones, but no condoms yet; anything & everything but do postal service. That service they are not interested, they must change the name POST OFFICE to PO Convenience Store Pte Ltd.
Don't believe about the parcel, the 'fun' part would be, you are not at home to receive it; have fun, the Post Office sells you cookies, "Buy Two, you get One free"!!:p
