Vodacom's very unhelpful and unequipped agents

Yesterday I tried to fill up my application for an upgrade on Vodacom's app, bur couldn't continue because of several glitches. I asked for assistance. This morning a friendly English agent calls me back but was unable to help. He put me through to another agent who also couldn't help. The 3rd agent was rude to me and eventually cut me off because I couldn't say my Afrikaans email address in English, she didn't even askms to spell it yet. I phoned back and the 4th person was still unable to assist me with the due upgrade. I am highly disappointed and dissatisfied with the Vodacom service for the first time in many many years!
