First support level is really bad, especially if you end up in India. But if you manage to escalate to level 2 or higher, it gets better.
Here, in France, I always say I do not speak english, I use to have someone in Ireland (they’re two french speaking ADC experts actually), and they are good.
Another solution is to involve your Citrix sales contact (if you have one) and/or try to contact your support technician manager.
