MBD Claiming June Payment Not Received

Terrible Service this institution debited my account on the 25/06/2018 with an amount of R570.00 to date they still cannot tell me what happened to my Funds. I was chocked to get a call from one of the consultants who was following up on the payment I think it was on the 05th July 2018 whom I advised that the debit order went off on the 25th June 2018 and she requested that I hold whilst checking the other system and she then confirmed that it was their system error payment was received. On the 9th July 2018 I got another regarding June payment not received. I explained the same story to the Cindy Ramparsad who then requested me to provide pop of which I did the very same day. I kept on following as I was worried what could have happened to my funds? Emails were sent from pillar to post with no joy. 16/07/2018 Linda Montzinger from MBD Credit Solutions provides me with the break down of the payment received however no trace of R570.00 debited on the 25th June 2018. Now who should make it a problem to trace these funds? Me or MBD, its like they are taking me for a ride like they doing me a favor. These are my Funds and I demand to know what happened to them as debit order was never reversed. I need my query to be resolved now!!!
