Ram to Ram The worst Customer service

My experience with Ram has been one of the worst I have ever seen. Been waiting for a parcel from Vodacom since last week. On Monday morning I receive a text saying that my parcel is out for delivery to my home address. I took it upon myself that I call them and tell them I am at work. They say I can't change an address with the I have to call Vodacom. I call Vodacom, they confirm that they have to send it to my workplace as I work at the SABC. Tuesday morning around 11 I get a call from Ram to confirm my work address and I even tell them my department and which floor. Today is Wednesday, I get a call around 14;00 from a driver saying he is at my gate (home address, which was changed) to deliver the parcel. I call Ram, the guy I'm talking with says it was not updated that is why the delivery guy went to my home address. After about 20 minutes I get a call from Ram saying that the driver says that I want a change of address. I tell the lady that I long changed that on Monday, why did the driver go to my home address when in fact I took it to myself to call them on Monday morning. She has nothing to say! She says I need to call Vodacom to change the address. I'm like you're saying I should do the same thing I did on Monday?
