Hisense technician did not close my washing machine

I bought a Hisense washing machine front loader on the 24 February 2024, mid may the machine was not working, called Makro and they referred the matter to Hisense, the technician came and opened my machine and told me it is because of roaches and they won’t do anything unless I paid. He didn’t leave any paperwork nothing, he didn’t close the machine properly. I called Hisense and I was told they will send him back to close it and they will send me a diagnosis report but up to today the warranty seal have been Brocken and I am left with a new machine that doesn’t work ☹️
