No response from Vodacom

Good day

I did a online upgrade last week and heard nothing. Today my data was switched off and when I investigate, I see it's because of my upgrade, but received nothing from Vodacom. I then realised that I have picked the wrong option.

Is there a way that I can cancel this upgrade (order ***)? I selected the wrong option ☹ and now my Vodacom data is disconnected.

I tried to email them, with no response, only to call them or talk to a bot. I tried the bot, but it's useless. I can't phone the call center because I'm deaf.

Please advise.

Kind regards
