Bad Service - Boulders Post Office

I have been waiting for a parcel from the 26th of October. I called beginning of October and the lady who was assisting me adviced that I should call again on the 7th. I called again on the 8th told that the parcel will be available today 12th. I understand the lockdown regulations that might affect the speed of the services. The complaint am having is the level of professionalism. Today I called more than 3 times assisted by different consultants. The 1st one put me on hold for more than 30 min. The second one did the same thing. 3rd one refused to give me her name. The 2nd one promised to call me back I never received that call. Now the phone is not answered. I am wondering how long does it take for someone to check if the parcel has arrived or not. This post office is the one in Midrand Boulders. I am furious due to the level of service they have and unprofessionalism. Please assist
