Terrible Customer Services

A parcel was posted on the 28th which was initially supposed to take 2 to 3 days. I went to postnet San Ridge Square on the 3rd of February to check and there was not even track of the parcel. One of the customer service agents took my details including my number and promised to call when it arrives. I never received any call until I decided to track it myself online on the 8th of February. The parcel shown to have arrived on the system. I decide to call and confirm on the 9th requesting the lady to contact me back. She did not. I went to check they still made me wait.. Same processes of searching. No apologies. I hats poor customer services. Please deal with this ASAP
