Deteriorating Service

I am very disappointed in the way my readvance application was at first with a consultant taking too long to deal with my application. Further to that, after my application was approved and the readvance paid out. However, from the interest rate I got from the recalculation, I got prime minus 0.58, with a confirmation that I will get a further minus 0.25 for being an FNB banker. I have forwarded my query to the consultant I have been dealing with, who told me that he will follow this up, but has gone radio silent on me now, as it has been since I started this application, where I have to be the one always following up with me to a point that I started dealing with another senior consultant. I have been with FNB for a long time and used to advocate for the bank, but the service has deteriorated over the years and it is because of the consultants we deal with. I have been patient, but things are readily getting half-a*ed day after day.

I have the further minus 0.25% in writing on email as given by the consultant. But for some odd reason, it is taking a long time for him to find out why is this not reflected on my home loan statement.

I want to apply for another home loan, but I do not like how FNB has been treating me nowadays.

I would like to know what is going on with this further discounted rate.
