Just had a reply from Plimus (see below)
Hello,
We have received the following inquiry in regards to reference number
******
We are forwarding it to the Vendor and copying the Customer on this email so
that this matter can be taken care of.
We ask that the customer please allow up to 2 business days for the Vendor to
respond.
If the customer does not hear back from the vendor, we ask that you forward
this email back to us so that we may assist you.
Thank you for your patience in this matter.
