Terrible Service - No Response - Multiple Queries

I called the FNB Home loans to query my interest rate. I was promptly helped by the agent and my rate was reduced by .02%. <br> When I queried as to why it was such a small reduction, the agent(multiple agents as I called multiple times) could not answer me and referred me to the Pricing Department. The Pricing Department has not responded to my query since the 23rd of January - that's 15 days!<br> <br> All I want is to know what I can do to be a better client and have my rate reduced further - so that I pay PRIME for my home loan. Is that too much to ask? I'm sure they use the criteria every day - why can you not forward it to me? I feel completely ignored by FNB and am now looking at moving my bond to a bank that appreciates me and my business.
