After 3 weeks readvance application not yet final

After over 3 weeks our re-advance application on our homeloan has still not been finalized. I have called 3 times to escalate, yesterdays escalation (***) was closed and no feedback given. Today I call them on ***, press 5 to speak to a Consultant (at 08:23) and get told yes the ref was closed but no resolution. Asked for a manager as I wasn't happy and the phone got put down in my ear! Our application for this was made at the branch on 23 Feb. Homeloans need to get their act together, 3 weeks for an existing customer's application is pathetic. Plus we cannot wait a week for this complaint to be resolved, can this please be expedited, both complaint and application?
