There is a serious issue with my purchases in Destiny 2 not being given to me. Who can I...

I've been dealing with an issue with my account not being given Silver I purchase on Destiny 2 for months. Every time I try to purchase Silver, everything completes properly and I get no issues with them taking my money, but I'm
never given the Silver I buy. I've spoken with Xbox and Microsoft support so many times that I've honestly lost count and every time, they give me the same answer that there is nothing wrong with my account and there should be no reason why I was not given
my Silver. I've also filled out numerous Missing Silver reports through Bungie support already, but they keep giving me the same
statement that they see no evidence that the purchase ever happened even when I provide them with my
receipt as proof. Is there anybody, anywhere that I can speak to that actually would care enough to look into my issue and help me get what I purchased?
