Annoyed poor service

Good day I’m very annoyed by the service received from Mrp online and City Couriers I have placed my order on the 21/11/2018 and have to date not received my parcel baring in mind I paid extra for eco delivery I called the call center on Saturday morning spoke to Asanda and to date she has not called me back with feedback as promised

Is this the way you guys treat customers????
