Bad customer service- Rediculous

I do not like to complain,

But waiting for months to get my Homeloan request serviced is been dissapointing, The original request was submitted in beginning may - nobody came back to me - calling the contact centre on several times, finaly after a month I recieved some feedback. again I had to call in, and the proposal was accepted - now 3 weeks later and several more calls the acceptance of the proposed solution is still not activated, and escalated again and again I do all the calling and again they advise that there is a technical difficulty.

Not held any of their a=service levels agreements - when I pay on time every time - worst service ever.

Thank you for still nothing
