Hisense service response is non-existent

I am trying to order spare parts from Hisense and the engagement and I've not had an accurate or timeous response since June 22. They've not ready any email correctly and not responded accurately. Gotten to a point where I eventually got a quote from them with instructions to pay, which is done immediately however since then I've had absolutely no communication. I've included their service and their complaints email throughout this challenging engagement, neither of which responded to me. I've tried to phone them and was told it is not possible to speak to their parts division as they only operate via email. I was also told that I am not able to follow up with anyone other than through email. Hisense, your service delivery is non-existent if a customer cannot engage with you and get a clear accurate response.

The payment was made on Thursday 1 July 2021 at 10:54 with proof of payment sent to you. Why could you not have confirmed receipt of payment and set expectation w.r.t. a shipping date yet? I mean, just acknowledge the enquiry email I sent you already!
