Proof of payment

i received a call to say, I have not made payment on my loan. I informed the call center agent to say , the payment is reflecting in my bank statement as debited by finchoice the lady responded by saying well she doesn't know that, I the customer whose account has been debited ask the trained call center agent how to share the proof of payment her response was send to info.....ohk I sent my statement to the info email address. I call the customer service the lady was so rude Sibongile. My airtime finished before i could finish the query. This will ruin my profile. How can i check if my proof of my payment was received
