MBD - PROVIDES NO PROOF/RECORDING OF PAYMENT

In December 2017 I was unfortunately retrenched, i therefore fell behind on my debts. Mid- year of 2018 i started repaying my debts monthly. However i had a loan with UDU and could not afford to pay my monthly installment as well as the arrears accumulated during the time i was unemployed. I had no contact from MBD until December 2018 who introduced themselves by sending me a threatening email and demanding payment. I was told i owe as of 3 December R16557,35. I immediately was shocked as i was personally trying to catch up on my UDU loan payment. However i acknowledged the debt and agreed to pay MBD a monthly amount of R770. I have paid R770 in December 2018 as well as R770 in the month of January 2019. I have requested statements tirelessly and have received nothing as of yet. I checked my credit report and see that both my payments have made no difference and the original amount of R16557,35 has now been increased to R16834 as per my Credit Report which is updated monthly. Please advise have both payments which add up to R1540 can not even cause my debt to decrease but increase by R277,35. This is honestly pure theft. I will not make another payment until i receive an updated statement every month going forward. I am making payment and nothing is being accounted for. I am dealing with Remona Abdullah i would like her to get back to me and explain where my money is going?
