No correspondence

I have a personal loan with Udu Loans. I have not been receiving statements for the past 3 months. I have tried contacting them with no success. I did a credit check and see that MBD has me listed for an amount of R31000.00 . I contacted them and they advised that they have taken over from Udu. MBD has not informed me of this takeover. I have never received a statement from them. The debit me every month as Udu and not Mbd. They have taken the installment on the 11/12/19 without my permission as my agreement with Udu was the last day of the month. The account is also duplicated on Transunions system as MBD has taken of the UDu loan account as they have now taken over. There it is showing Udu active with a balance and MBD active with a balance. This is not acceptable.
