Post Office- poor service

An order was placed last year in August, I continually followed up with the tracking of the parcel. Mid December the parcel was receipted in at the Germiston Hub. After numerous requests to the company I purchased from I was advised it was at Alberton. Beginning of January I went to the Alberton post office and after waiting more than 30 minutes I was told it had not been received yet. The company I purchased from confirmed again mid February that the parcel was at Alberton post office. We were away so on our return I went today to follow up. Firstly they have no computerised system and i was told to go through various books to find my order. I did eventually found it and I noted that it was received and written into the book on the 27th December, even though on the 5th January I was told it was definitely not there. I then had to pay an additional handling fee. When I questioned why the Post Office staff do not check receipts and why no communication to us confirming that the parcel had arrived I was ignored. Eventually another lady came and told me they had sent sms's advising us. When i told her we had not received any messages she said maybe their message system is not working.At the time I was there 3 other customers were complaining about the same bad service. Staff at the Post Office needs to start realising it is a privilege to have a job andstart treating their customers the way they should be treated as we are paying their salaries at theend of the day.
