Good luck with that
Several years ago when I last dealt with them on a regular basis, CWW was staffed by one or two gems surrounded by large number of buffoons. If the sources are credible and they can be a "contender" then there's suddenly a very large number of contenders out there.
I could be wrong - most of my experience is quite ancient, and most was with one specific department, although contact was regular and for many different infrastructures - but somehow I doubt it's much different now.
The only thing of course is a lot of potential business that could go to more nimble, proactive and specialised providers will go to Voda as the decision makers will be blinded by the name.
