FNB Home Loan / FNB Housing Finance

I made a payment to my home loan account on the 20/10/2021 they payment was not allocated. I called in on the 27/10/2021 they requested for proof of payment. I sent it to them, and still haven’t got any feedback today is the 18/11/2021 it’s been almost a month and the payment has not been allocated. This is terrible service. I still have not been assisted I’ve been calling the home loans department every 2/3 days to follow up and they keep telling me it has been escalated to the finance department and they will allocate it within 24/48 hrs. I still haven’t got any assistance from anybody. No email, no feedback as to what’s going on. This is now reflecting negatively on my credit score as if I am making payments late when it is paid on time. This is my favorite bank but the service I’ve been getting is appalling.
