Very poor customer service and upgrade department

<p>I attempted to upgrade my contract with vodacom - i have spoken to customer service agents and upgrade agents and the service given was the worst I have ever experienced. No one calls back, no one follows up, no notes are taken. No one is accountable for their actions. I am a great payer and if this is how they treat me then wow. No one could organise an upgrade ............................. waiting for the phone next week that is what i was assured by the last agent I spoke to.</p>
