I have two organisations who purchased Microsoft Office via Connecting-Up.  Both recently had me deploy new PC's across the organisation (the larger had 12 new Desktops, the smaller had 4 new desktops) with Windows 7x64 Professional.

For both customers:

1. During deployment they received the relevant notifications from MS regarding VL portal access
2. They logged in and downloaded the ISO's and license keys from the portal
3. The products was installed and license keys entered
4. MS Office 2013 reported at each site that activation was successful.
5. 30 Days later the bigger organisation began getting notification warning their products weren't activated.
6. Keys were re-entered, and each machine confirmed the activation was successful
7. Last week the bigger one again received notification Office wasn't activated and again switched to Trial mode
8. The smaller organisation has just reported the same problem, their PC's were deployed appro 30 days ago and the product is reporting it wasn't activated.
9. I have uninstalled the product and reinstalled from a separate fresh ISO
10. I have created a Admin Install point and preconfigured the settings (lic key, activation) and it seems to have made no difference.
11. The bigger client has some machines that are part of a domain at the customers HQ, the others in a Workgroup at a remote site

I have

1. Called MS Support who said I needed to contact Product Activations.
2. Called Product Activation who gave me an address MAKADD..... and I already new this wasn't their area.
3. MAKADD confirmed this when they responded.  They advised need to call MS Support.
4. Called MS Support who transferred me to Volume Licensing, who said I need to log a support request.
5. Repeated today alone for 3 hours, and this isn't the 1st time I have ridden this ride

I don't know who to call to get some common sense.  I have many many other clients with MS VL licenses and we've had none of this sort of issue happening, purchased thru other resellers, the only common link is Connecting-Up.

I have been told the client needs a Software Assurance ID to sort this out, or pay for support, but here in Australia if the product doesn't perform to expectations the vendor must resolve.
