It has been very easy for us as an agency using this software from CROWNPEAK since day one! They are always willing to help when needed - even if it is something off-topic like scheduling meetings in another timezone or other countries around holidays (which happens quite frequently).
I don't think there really was anything bad at all while working together; they were extremely helpful throughout our partnership relationship of several years now. Our only issue we had during those two plus years which didn’t affect customer service but rather technical support came up once again after having moved offices twice already. This time however everything went smoothly and without any problems whatsoever thanks to both teams' efforts.
