8 Calls and still no one gets back to you

I have Hisense TV and the remote broke, and have tried all universal remotes without luck, I have now tried getting one from Hisense direct, oh my word, this has to be the most frustrating and inefficient company to deal with. Called 3 times last week and eventually got through to a lady called Alicia who said she would call be back the next day. Having not heard a word, I then tried calling again yesterday, 1st time after hanging on for 5 minutes the call is cut, second time I held on for 6 minutes with the phone just ringing away, so I hung up, the 3rd time I am told by the switchboard lady that they are not answering because they are all on lunch I ask to speak to a manager and am told (usual response these days) they are not available, but she would take my number and get someone to call me back. Of course this did not happen. I then emailed a gentleman Rubin explaining my issue, giving my number and expecting a call, clearly they are not bothered as his response was \please call me service team"are you kidding"
