Unreachable and not capturing information

I am so upset with the DSV call centre in durban with this number ***. If they don't answer your calls. they don't capture important details you want changed on your delivery. Firstly i called yesterday informing them that my delivery address needs to change due to my work address changing. The receptionist took my Id, Name and cellphone number and promised to have it changed for me. This morning (05/08/2022) i called only to find my address has not been changed. Mind you i start5ed calling at 7.30am i only had response at 8.30 am. The lady took my details and would contact the driver with the phone. The time now is 12.16pm no further communication. I cant get through to them im just getting the receptionist. I knock off at 4.30pm and i need this phone urgently. been waiting since friday last week 29 July.
