Rude consultant

I have an account with ok furniture which I opened in August 2021. Now the issue at hand is in September 2021 I made a payment via house and home which was first payment, then in October 2021 I went to house and home again to make a payment then I was told that I am no longer owing the account the I asked how, then the lady who was helping called the head office to enquire about my account and the person she spoke to also said that it was on the 15 of October 2021. I then went home puzzled because I only made 1 payment how is that, that I no longer that account. On the 16th October 2021 I called ok furniture in potch then I spoke to a white lady who also said the very same thing that my account is not owing. I then went to ok furniture in klerksdorp to enquire then they also said the very same. So I decided to leave it like that because I could not understand then after 2 weeks of trying to pay my account I got a call from OK that I did not pay the account and they wanted to know the reason why, again I was confused by that question because I was told by them that I no longer owe the account. Then fine Inade arrangements to pay 1000 every month to cover the areas on the account of I have been doing it honoring my payment arrangement. Then on the 15th of February I called the head office to ask for banking details and I spoke to a lady by the name of moli and she gave them to me but when I try to make an eft the account details were rejected. Then I went to make a payment at shoprite of 1000 as promised and Moli did call me to attest that the payment was received and she asked me again when will the other payment be received then I said again on the 15th of the following month which is March 2022. Now today the 08th of March 2022 I got a call from a very rude lady demanding payment thought I have made arrangements to pay on the 15th March 2022. I don't appreciate her tone when speaks to a customer as old as I am. I felt harrased by this rude young woman. Ok furniture please deal with your consultant or otherwise am going to refer the matter to the ombudsman
