City of Cape Town refusing to pay back my money

I am so disgusted by the treatment i received from the City of Cape Town municipality , i was told that i am owing R77872.63 as loyal citizen i paid the money on the 26 February 2021. I discovered that on the statement that i received in March 2021 that in fact the City of Cape Town is owing me . I filled the necessary documentation & emailed it to the since today the money is not deposited in my account instead the are sending me from one pillar to another . I also explained in the email that my husband is no more but the are saying that he need to sign the document too. I gave them the proof of payment , confirmation letter from the bank, bank statement ,my ID, death certificate for my late husband, executor letter and the request form which was signed by my bank.

The treatment i am receiving from City of Cape Town is acceptable , i want my money back this nonsense must stop. I am starting to think that i am treated like this because i am black woman . Hellopeter please intervene in this matter.
