Hisense Dishwasher - after sales services sucks

I have had back and fourth communication with the Hisense sales department. My dishwasher was damaged, and I needed some replacing parts (nothing with the motor, spilled something on outside which made it look ugly). Firstly, after numerous emails, I eventually got to order the parts. Upon delivery, the parts were for the wrong machine, as well as the incorrect parts, not the ones actually ordered. I have been struggling now for 2 months to return the parts, to order the correct parts for the correct machine. I have sent so many emails, with either *********** replies, or just no replies. Along with my disgust is the fact that my warranty is apparently now void, as I have to replace some plastic parts, which does not have anything to do with the mechanical working of the machine. The machine was a week old when a builder spilt thinners on the machine. I wonder if a review on hellopeter will ensure that I do get some spare parts afterall.
