Unreliable and Rude

My online shopping package (paid) was delayed by 10 days. Tracking details showed that the delay was because of "Consignee not available" 03 times. However no one attempted to contact me on cellphone all 3 times. I picked my parcel by hand and tried to lodge a complaint but the manager rudely declared that it was not his job to deal with every petty complaint. Even blamed me for lying about missed calls. Tried to call help line, call disconnected when pressing '0' for operator. Un serious attitude towards customer service and complaint management
