Vodacom and RAM couriers

I am at my wits end with Vodacom and RAM couriers! Incompetence at it's best! Try get someone to really listen and follow up is an impossibility! First time round tried to deliver my modem for fibre several times, I tried numerous times to change the delivery address as I am not at home during the day( surely best to arrange this and confirm before sending your driver on a wild goosechase). It reflected on the tracking page that I changed the address but keep arriving at original address. Eventually package sent back to Vodacom. Now after speaking to Vodacom and changing the address they have again dispatched it to the wrong address. If you phone RAM they just blame Vodacom and if you try contact Vodacom you speak to a robot, if you're lucky a person...but clearly they can't do any better than the robot! Feels like level of a human affairs office in South Africa! Can't believe how anything gets done with this level of people employed!
