Misleading OnStar Renewal Offer and Frustrating Customer Experience

This sounds so familiar. I have now been bounced around several times between chat and the phone and it is absolutely frustrating. I am glad I found this thread.

Same pattern on my end with the 2023 GMC Yukon Denali XL:

• Renewed early June with a 50% off coupon that was emailed to me.
• Ended up on the wrong plan - not the OnStar One + Super Cruise bundle I need.
• Tried to upgrade on the website → checkout charged full price with no credit applied.
• $199 in GM Rewards I applied to the wrong plan still have not reappeared.
• Multiple phone calls and chats, each rep transferred me, nothing fixed.
• Got placed on a 3-month plan I never agreed to, then cancelled out of frustration.
• I just received the same 50-ARCRUISE promo again today - same code, similar problem.  On-line checkout won’t even accept the code no matter what plan I choose.  I even used the link provided in the email.

All I am asking for is to be switched to the annual OnStar One plan with Super Cruise, with the $199 inGM Rewards credited and the 50% coupon honored on the correct plan. I am asking for nothing free -  just the credits I already paid to be applied to the plan I actually need. The fundamental issue is the original payment and coupon were never correctly applied to the proper plan.

Service has already ended and I am now driving without Super Cruise or any connected services.

I’m only interested in the "send us a DM" response if you are the team that can actually fix this end-to-end. Please take my money. Why are you making it so difficult? I want to stay a customer - I don't want to trade in my Yukon, but I am getting very close. I've been browsing other options and may purchase something else by week's end.
