Bad service experience

Bad service and complaints about handling, my parcel D*** was dropped off on the 16th July on a 3 to 5 days to arrive by the following week on Tuesday. When i contacted the agent via WhatsApp, there was an issue about strike affecting couriers, but my question was why didn't they communicate or let us know about the latest changes, secondly the agent was rude answered once in person sent automated replies that are not anywhere near to my question and cut our conversation short before i could even get a straight answer as to when i should expect my parcel. The company is filled with unprofessional staff with stinking attitude, failure to take responsibility while handling valuable items and they still act like they dont need us. They have definitely lost a client, its one thing experiencing a problem but its another when you not showing care nor takin accountability, it is after all their company and should care for their clients now they act as if they doing us a favor, im so mad right now. I feel so disrespected. I need my parcel and take my business elsewhere where it's appreciated.
