Terrible Service from Hisense Head Office

I bought a Hisense Dishwasher 2 years and 2 months ago. After 2 years the bottom tray started rusting so badly that the pieces are falling off. I called Hisense and the Customer Care Lady informed me that she can only send me a quote! She also told me that I have to air my dishwasher out every time I use it. Of course, I do that! She refused to put me through to a manager or to even look further into the issue even after I informed her I was going to report this to Hello Peter and Social Media. I told her the call was being recorded and she threatened me saying it is ******* for me to record a call without letting her know. I wasn't recording her, Hisense was recording me, which is what I was trying to explain to her. I told her not to threaten me, and she continued telling me what I was doing was *******. I then phoned back and spoke to another assistant. I have her name and asked her to put me through to a manager, she put me back to the board, so I had to phone again, spoke to the same person and got nowhere. Please can someone call me to sort this issue out, otherwise I will be going to Social Media. This kind of service is frightening.
