In the past I contacted a different VAR to my current one and they just said it was very unusual to want to change VAR.
However just a few months later its turns out my current VAR purchased them, so I thought maybe that was why they fobbed me off.
Recently I contacted another VAR, they are local to me - they have a more local office than my currect VAR.
I followed up the email with a phone call when they didnt respond.
They promised to call me back, but they haven't.
I get the impression from USA users that there is a quite a competitive market between VAR's over there. In UK while there are quite a few VARs all claiming to cover my area there seems to be no competition. The VAR you chose is the one you have. They are no interested in you if you have a current VAR.
That, I think, is bad news for customers!
