Bad service from CCD Couriers

I have never experienced such bad service and unprofessional behaviour from call centre agents. I have been calling from monday to get my Rain delivered. Finally someone said it will be delivered 05.07.23 I call at 8h20 and than i am told its escalated for emergency delivery but someone who has to authorize it hasn't. I was transfered to another department holding for 15 minutes. I have hold for 20 minutes and the consultant call the accounts department and spoke to Sanduliswe/ Sandiliswe who refused to speak to me and told the consultant to book delivery for friday
