Dell Account help

I recently have taken over the responsibility for the company I work for on making the IT purchases. I was still utilizing the previous persons account and Dell rewards were still being applied but then the dell rewards and the machines that were being purchased were no longer being added to the account because my name was transferred as the contact person, but this wasn't changed on the account. I managed to make an account with my name and it appeared that most of the information from the previous account was automatically merged by Dell? Well, it appears I am gaining Dell rewards, which is great, but they are not showing up within either account and the only way I am notified about any rewards is through email when they are about to expire. It also appears that the machines that are being purchased are not automatically added to either account device list. (The purchase however does show up on the newer account under my name).  I really need help with this issue. I would really appreciate someone reaching out to me. I have tried contacting Dell in many ways and no one has been able to direct me or help with this issue.  This has become pretty frustrating since it seems we are missing out on utilizing Dell rewards, and is now taking time away from my other duties while I now have to manually add each machine into the account. I don't know if any of this makes sense, But I'm not even sure what has happened here. 

Please advise on how to help with this situation.
