ENEB to UK top up masters possible?

[armado]

Just emailed several UK universities to ask if I can use my Isabel I/ENEB MBA for their MBA top-up program.
So far, I have received two responses:
1. From University of Plymouth:
"Good afternoon,

Thank you for your email and interest in studying at the University of Plymouth.
In the interest of the MBA top-up, we would need to see you have 120 Level 7 credits, made up from other qualifications that aren’t just from a Masters degree that you already have.
We cannot accept the credits from a master's course. This is because those credits have already been counted towards the master's qualification, so they cannot be used again towards the MBA. We can only consider those credits if they were not awarded the master's degree (i.e., PgCert, PgDip, 140 credits from master's study, etc.).
If you have any other Level 7 qualifications, please do send them over and we will be able to look these over for you and confirm if it is something we would consider acceptable for entry requirements.
Kind Regards,"

2. From Leeds Beckett:
"Hi .........

If you already have been offered a degree you cant use those credits to get another degree."
