Real person Executive Resolution

I have spoken to 4 people in the past 2 months and no one is helping. My client discontinued their relationship w their old accountant in 2019 & the accountant continued to bill the client until 02.2021; without their knowledge. I brought this to QB’s attention and was told in 3 recorded conversations and 1 email that my client would receive a full year refund. Every time the manager or rep calls back or emails 6+ hours later to say that’s not the case. I have told my client 2x now that she is going to receive a refund. I need to speak to someone stateside in executive resolution to solve this. I am tired of being jerked about by QB’s.
