QB Payroll Department Making Mess of My Books - How do I get support escalated?

The payroll department has ROYALLY messed up my books. My books were perfectly correct, but when I transitioned to the QB payroll module, I entered the historical paychecks for the year. The system did not load that information into the payroll module. My chart of accounts was all correct, but the payroll module did not match my chart of accounts. Customer service had to submit a correction request. It took about a month, but the payroll team called me regarding the correction request. I filled out the template they sent me with the data that needed to be added to the payroll module. They entered the data and asked me to verify they entered it correctly. Upon checking, I made them aware that they mis-keyed one of the FUTA entries by $3.00. They keyed $4.50 instead of $7.50. I verified that the data I sent them was correct, and it was. Now, they have not been able to rectify their error. First, they adjusted Medicare, which was never incorrect to begin with. Which led to the payroll system requesting a refund on an overpayment of Medicare taxes, which were not actually overpaid. Then they did an adjustment on the FUTA for -3.00 instead of +3.00. Now, one of my employees has a duplicate paycheck showing up, so my chart of accounts are ALL incorrect at this point. I asked for them to escalate my issue over the phone and was told no and the representative got an attitude with me. This was after I patiently gave her 3 tries to get it correct and she kept messing it up further each time. This is UNACCEPTABLE. They are messing up my books, but yet don't give me the ability to correct them since as a user, we cannot do the payroll correction entries ourselves. Now, they tried again and asked me to review. Upon review, it is still incorrect. I bring it to their attention and then they tell me that my FUTA calculation was wrong. My FUTA calculation is correct and they keyed it wrong. The entire problem is that they mis-keyed an entry by $3.00 and cannot correct their own error. I want someone to listen to the phone call recording, and to review the e-mails, and to FIX THIS.
