Issue with Payroll Upgrade due Sales Team Error

I have a story to tell and am in need of help resolving the problem.

My company was contacted in January regarding options for upgrading our Payroll Subscription. After meeting with a Sales Rep and hearing the offer, benefits and all the bells and whistles, we agreed to upgrade to Payroll Elite (from Core). (We also have a QB Plus subscription)  On Jan.9 2025 the Sales person processed our upgrade and charged our CC. During the conversation they indicated that they made an "error" and would be refunding and recharging our account to make the correction. There have been no corrections. Numerous emails (all unanswered) and Numerous phone calls to "Support" "Billing" "Payroll" and "Sales" have been unsuccessful in getting this situation rectified. I was made aware that the Sales person created a "New" Business ID and the money we paid went towards that. However, I am now being told that in order to rectify the situation, we would receive our money back and Not receive the promotion as promised. This seems outrageous. I'm no expert, but I would think that they should move the upgrade payment to the correct Business ID, along with the promised discount and perks, delete whatever business the Sales Rep created in ERROR, AND refund our company whatever they have been overcharging for the past 3 months. I'm so confused. Thoughts???
