Vodacom fails to deliver...again

Vodacom has been nothing but a host of problems of the past 2 years. The most recent of which has been being unable to process online upgrade requests. (it didn't go through see my previous review) Which they phoned me to resolve (which took forever because their operators are unable to record an address) but when we arranged a time with the courier so that we could get the documents they requested (which is completely new and seems a little unnecessary) the phone never got delivered. Now I would still like the upgrade at the agreed upon price but would like the phone to either be sent to a store for pickup or to arrange a new delivery address but am unable to figure out the process for doing so.
