Am I going mad?

I’ll try and keep this simple. I have 3 IPs worth around $1.2M, a rental income of around $47,000 pa and a $65,000 annual salary. I have a Rocket Investment Loan (Westpac) with a balance of $445,000 and available redraw of $35,000. I approached the bank and asked them how much more they would lend me. They came up with $450,000 more and popped it into an Equity Access Loan (LOC?). As well as the standard 0.7% rate reduction for being on the Premier Advantage Package, they knocked off another 0.25%. So on the EAL I’m paying 7.02% instead of the standard 7.97%. Not only is the rate better than the 7.12% on the RIL, but the loan suits me better in that the limit is fixed, no min repayments etc. So the bleeding obvious hit me and I decided to call them back and ask them to merge the two loans into the EAL and remove the RIL. In effect my credit limit should have become $930,000 (right?) with a $445,000 debt and $485,000 in available funds. When the loan went through I went online to check it. My RIL still sat there untouched, but they had added $480,000 to my EAL credit limit. I now have available funds of $35,000 (RIL) + $930,000 (EAL) = $965,000!! At first I couldn’t get my head around it. Then I thought it must be an administrative error and will soon be rectified, but a week later nothing has changed. I even rang the Mortgage Centre and tried to explain it but they couldn’t see the problem!! Please tell me I’m not going mad.
