- While replying to a specific Local Guide (LG) or to mention a specific LG, please use ‘@’ followed by the respective LG user id. You will get this by typing ‘@’, then a list with suggestions appears, e.g. mine is @Kumaarsantosh.
Now for your specific query about Google Maps Local Guide Gift shipped but not received, did you get any confirmation from the local post office or courier services about your delivery shipment?
Usually, it takes 4 to 6 weeks to come to your doorstep once shipped.
Having said that there might exist some issues/gaps in the whole process which I have responded earlier here.
You might check that if that helps.
Keep building a well-informed community stronger 
together.
JAI HO!!!
