Double Debit

This start with my account being debited by Telkom for R1025 on the 26/09/2015 for my mobile broadband service, then it was debited once again for R1025 again on the 30/09/2015 both amounts was taken from my account and I got the bank statement to prove it. Also I went onto Telkom Chat assistance and one of the agents I spoke to advised me to get a bank statement so I can send it to them, I got the statement online and I told the agent this and they said ok no problem, when I said where do I send it to they ignored me and ended the session. Then I went on to the chat a again and this agent advised me with confidence that the account was debited once even though I got the proof, the second agent could not be bothered about me saying I got the proof infront of me, not once did the agent say send it to us to see they just ended the session as well. This double debit caused me alot of trouble as it stopped a few other debits from going off and now I incurred bank charges and extra charges for the failure of the other debits, I want to be compensated accordingly, I never had issues with you guys but this type of service is terrible, I got screenshots of both my conversations.
