VWSA Terrible Servive

I have lodged a complaint with regards to my air conditioning system a month ago and have not heard a word from VWSA other than the automated email acknowledging my email. This, after I phoned them and spoke to them personally before sending through the email. I phoned in again to check on the status of the issue about 2 weeks after the initial call and email, and was told that they are sorting the issue out. I am utterly appalled and disgusted by the service that I have received from VWSA. The air con issue still hasn't been solved and quite frankly, it doesn't seem that VWSA wants to solve it, despite them saying they will sort it out as soon as possible.
