i have an issue with my landscaper
(1) He changed the quote after accepting the estimated quote two weeks later.
From my understanding, the quote valids for 30 days and can't change it after telling him to go ahead but the issue is that he has added this paver quote in the original quote from May.
However, the original quote he gave me only includes deck, lawn and other paver which has totally different name & is different brand.
I have also email from two weeks ago saying that he is updated the quote for new items and the new paver quote was there.
(2) Can he also charge 3 sqm extra if the deck's actual measurement is only 30sqm that is already include the frame, service, side end and the whole structure.
I am told that the ecodeck has to cut to build the size I want and there is extra part that cannot use anywhere anymore so he charged me for that part as well. As far as I know, the quote should reflect all those costs for the part he has to cut & throw away too.
(3) Can this issue be reported to fair trading if we cannot negociate?
Should I report before making final payment (or) Should i pay first and report later.
I would be so sooooo grateful to receive the advice.
