Very poor service from the homeloans department

I have been contacting them with regards to a term extension on my home loan since the 2nd of june. First they told me I would get feedback within 10 working days. After the 10 working days were done I still have not received feedback and phoned them again. It was escalated to a manager and they said 2 days for feedback. I have phoned them 5 times now since the 2nd of june and I still have not received any feedback and everytime I ask to speak to a manager they are busy in a meeting. I am very disgusted with the level of service I have received.
