Zoho Support for Desk - NOT GOOD

Zoho Support for Desk - NOT GOOD

We have been using Zoho Desk for some time now and for basic tickets its been good. But when I try to talk to their support on the phone (yes on the phone) the results are not good to say the least.  There is a huge language barrier combined with a poor connection or background noise on their end.  For a product that seems so robust and developed why is it they have this issue?
