How Do You Contact Microsoft Cashback Support?

Hi all! I've been in this battle for a while now and getting nowhere. Here's a rundown of what's been happening:

• I had an incorrect cashback amount credited to my account, so I reached out to support
• The first support person asked for more information and gave a list of what they needed
• I responded with the requested information
• After a week, I wrote a new ticket since they said I should have had an answer within 24h. In the new one, I ensured it already had all the information requested so it wouldn't be asked for again
• The new ticket was answered within 24h and closed due to the old one being open
• A few days later I wrote in again with all the information since I still haven't heard back on the first one
• This ticket was responded to asking for the same information I put in the ticket request. I responded with the information again. I'm guessing they had given a canned response in the beginning
• No response so wrote in another ticket... this time organizing the information requested previously into a much more prominent way
• This ticket gets responded to asking for.... you guessed it, the same information again!
• This ticket goes unresponsive once I re-send the information again...
• I write another ticket. This one is closed because the original one, still unanswered, is "open"
• I just sent in yet another ticket with the same information I keep sending that keeps being repeatedly asked for again and again despite sending it

I'm honestly at a loss of what to do at this point. It's very clear at this point that nobody is actually reading the tickets; they read a few words and then give canned responses. But they also aren't reading the first few words because if they were they'd see the requested information at the top of the tickets...

Is there a phone number I can call where I can speak to an actual person? Some way to escalate this? This has been an uphill battle and I'm just hoping to finally get it resolved so I can move on.

Thank you!
