Tired of Incompetence/Bad Service

So we're in the process of finalising the purchase of our house, which is all very exciting. However, the administrivia is quite the opposite, as illustrated in the following series of events:
  1. A few weeks ago: Our mortgage broker sent our First Home Owners grant documents to St George, our bank. Our mortgage broker then called to confirm that they had been received.
  2. A couple of weeks ago: I called NRMA (our insurance company) to ask them to raise the building insurance amount to the amount specified by the bank. (My original figure was obviously an underestimate.) They told me that this was all done, no worries.
  3. Early last week: Jen sent the insurance documents to St George. She also emailed our solicitor with a request to settle a few days earlier.
  4. Last Friday: No contact yet from our solicitor, so I called his office to confirm that the request was received and actioned. He's not in the office; apparently, he'll call me back on Monday morning.
  5. Monday afternoon: No call from our solicitor. I called him late afternoon. I noted that he mustn't be receiving our calls and emails. He noteably neglects to mention the email, but was surprised about the call on Friday. He told me that St George apparently haven't received our insurance documents (see 1), nor our First Home Owners Grant documents (see 3).
  6. Tuesday: Jen had to drive to visit our mortgage broker to sign new First Home Owners Grant documents.
  7. Wednesday morning: Jen called NRMA to ask them to fax our updated insurance documents to St George. She discovered that apparently, our record states the old insurance amount instead of the updated amount (see 2). Our solicitor called me to tell me that the received fax was missing some information. Jen subsequently called NRMA and they said that the information was correct in the records but that the fax was somehow incorrectly generated.

All is now finally sorted, but.... aaaaaaaaarrrrrrrrrrrrggggg!
