Wantitall Broken arrivals online orders

<p>I have ordered a very expensive (XPERT OMATIC) Electronic PH meter from Wantitall.com that was over R850 that took 15 workdays to arrive. When it arrived yesterday i started my alchemy project. My partner and i tried several times to calibrate the ph meter, we also watched on youtube and followed the instructions on the back of the package to the T. The PH meter is jumping up and down, never giving the exact or same PH in the solutions. I am very unhappy spending money i didnt have on a device that does not work. This is not acceptable </p>
