Nonexistent support from xbox/Microsoft

Since I bought my series x in March'21 I've been unable to retrieve one of my digitally bought games on the Microsoft Store. I've been in contact with xbox support more than 10 times to try and resolve the problem. Each and every time the agent tells me the matter will have to be further investigated and then no further feedback is received. In addition to all of this Microsoft's contact center has been offline for over two weeks now and I have been unable to contact them
