Basically, we had a blockage which cost us $400 for them to locate the find.
We were later told that it would cost a further $1,400 for some pipe section (underground about a metre deep) that the council either forgot to close properly (or was knocked out by nature) that caused the pipes to collect debris over time and therefore blocked the pipes. Then they added another $4,400 because apparently the piping leading out of the house to the main was broken (down where they dug a hole???). But of course it wasn't there fault - it was a tree root dangit!
To further put pressure on us, they told us that the actual job was not $4,400 but $6,200. They then did the old car-sales-pitch: if we had the tree root cleared and replaced the pipes job by 5p.m. on that day, they would waive the initial $400 and $1,400 we'd already paid for the first two jobs, which would then bring the job down from $6,200 to extra $4,400. Thanks guys. How noble of you. To reassure us they told us another plumber would quote around the $6500 mark, so hey, you might as well go with Omega, because we'd already paid $1400 on the first two jobs, which they would waive if we stuck with them and paid $6,200 for all 3 jobs. Whereas if we were to switch plumbers now they guaranteed that we'd pay $400 + $1,400 + $6,200 = $8000.
Not one to get ripped off, we called a local small scale plumber who services both the West and North Shore, explained the situation and heard them chortle in disbelief. Needless to say we went against Omega's advice and went with the genuine, small-time business. If I could rate Omega on the negative scale I would. If I could be bothered to go to ACA or if Today Tonight was still around I'd do that too. But all I'm saying is stay away from Omega. If they cannot be bothered doing the job they will just over quote. If they can be bothered doing it, they will over quote anyway. A really unethical business.
