Reverse transaction on my account

I requested a cancellation of the 5G router service from rain on the 23rd of October 2020, ticket: *** & *** assisted by Portia Maimane, Nubuhle Mabe, Yushdhir S and also one of the agent that came to collect the router. Rain debited my account on 1st of November for October. Then they continue to debit again on the 2nd of December. I logged a ticket: *** on the 2nd of December requesting to reverse the transaction made on my account. No one from Rain has contacted me or reverse the transaction.
