Vodacom just can't get the basics right!

Upgraded my contract almost 3 weeks ago. Vodacom supp**** the incorrect delivery and contact details to Ram couriers. The Vodacom person - who I won't name yet - has just stopped returning my emails. The device has been "returned to sender" because Ram can't contact me. Between Vodacom and Ram - I can't quite figure out who is more useless. The cherry on the cake is Vodacoms @#$% call centre. Dropped calls. There should be a zero star option. I try and avoid dealing with Vodacom - perhaps once every two years. AND THIS IS WHY.
