TERRIBLE Service from SAMSUNG electronics

I have been struggling to get Samsung to send me a simple invoice to have a technician come out & look at my damaged TV set. Despite numerous calls since 12 March 2018, I have yet to get any meaningful assistance from them. I got the impression, after the first call that they are keen on providing good service but subsequent non-action by them tells me that they do not care. I am forced to deal with this and follow-up endlessly because getting a repair from a non-accredited repairer has the potential for even greater disaster. I am stuck.
