Aussie Post slow to deliver

Just wanting to know if other sellers are having problems with Australia Post taking longer to deliver items.

 

I send large letters. On Monday at lunch time, I sent an Express Post letter from Northern NSW to Victoria. It should have arrived for the customer by Wednesday, Thursday at the latest.  The item was delivered today, Friday. 

 

Also, the last 5 weeks, I have had 6 customers contact me to say they hadn't received their items yet .... 4 days after it should have been delivered, thye recieve it.

 

Does anyone know what is going on, as I have never had this happen before. There is nothing on the Australia Post website.

 

Have they changed to delivering letters 3 days a week and not told anyone. 

 

I am concerned about the extra sales near Christmas as well if this keeps happening.

 

Thanks 🙂
