My tolerance level is low today.
You obviously don't know what you are talking about so, follow the old advice of :
It's better to sit quietly and be thought a fool than to speak and remove all doubt.
VM's service is dependant on which region you live in, in a previous job you couldn't use VPN connections within some regions.
The constant sources of crap with VM seems to be their Indian call centre for the following reasons:
1: The VOIP system that is either incorrectly configured, or bandwidth starved
2: The inability of said staff to understand that when you say you want to reduce costs, they try & sell you a more expensive package
3: The call centre's inability to understand any form of regional accent
4: If it's more complicated than turn it off & back on again it's a 3 day wait for their 2nd line staff to contact you (who then say have you turned it off & on again)
Once you get a hold of the UK staff things do improve though.
I dare say that if the Indian staff got some proper training it would probably help matters a lot.
