Refund me please

I’m tired of the unprofessional service received from Vodacom, I’ve logged a query on the 1st of March notifying them that my online payment went off twice and requested a refund however Steven and his supervisor Ilhaam has been sending me from pillar to post for a mere refund of R227.40. I’ve sent several emails to ***. I don’t understand what’s the fuss to refund when both the agent and supervisor confirmed that they can see the double payment reflecting on the system. Please refund my payment immediately.
