Bad service

Hi.

They sent me a discounted settlement quote for my fasta account R3339.43 which I paid on 15 August 2022. I then asked for proof of settlement and closure. They told me that it will take two business days to reflect fund even though I did immediate payment option, then they will give me the closure and proof of settlement for the account. I have since been asking for the documents but not getting any feedback. Instead they keep asking for my ID number to locate my account and ref. I have been giving but after that, I get no response.
