Delayed parcel

I have booked a courier with RAM only to realise that i have used the incorrect number i then called to rectify the number of which they assured me that the number was rectified , I never received my order on time i had to call again to ask why it wasn't delivered they said the correct number was no updated they forgot to update . the lady at the call centre by the name of Andile kept me waiting for more than 10 minutes to find out why my parcel was not delivered upon her return she hand up on me while i was still asking . terrible service from RAM
