Disgusted by the lack of Customer Service

I have been trying to contact the SA Post Office on ********** 502 from last week, to find out where my parcel is. I eventually emailed them at ********** 28/09/2017 - to date I have had no response. The website information says 'missed delivery' and has not been updated from 26/09/2017 so I am unsure when this will be delivered to my nearest Post Office. This morning I dialed ********** 502 and was on the line from 8am to 8:32am until I finally hung up. I am appalled. Does the call center switch on at 8 just to say they are "active" then everyone rocks up to work later? Because this is the worst call center experience I have ever had. Does the Post office not adhere to SLA or AHT? You guys have jobs, please appreciate it and do what you have to, to get your work accomplished and service your customers - its not so much to ask, when there are so many people desperate to have a job.
