Replacing geyser

I had my geyser replaced so many time by Brackenfell plumbing that I am convinced they are damaging it just to come back. With the last replacement of my geyser, they damaged the wall on the other side. Sill waiting for it to be fixed. The pipe burst on exactly the same place they fix it before and again they made a whole in my wall...still not fixed or painted. The best of all is they don't move a muscle before your access fee are paid, but now when it is on their cost, you must wait for ever!!!
