Onstar module malfunction/ refund

I recently recieved a recall for my 2025 gmc Acadia stating the onstar module was malfunctioning. This has been an ongoing problem since august. I haven’t been able to access my benefits that entire time. I just recently got my onstar fixed and now it’s expiring. When I spoke with an agent to get my onstar fixed over the phone the gentleman told me they would give me a credit for the months I went without.
