Hello,
Some US reseller provider have these end-user support. But please remember, the customers will know your provider better than your own company. In the end, most of them will jump ship
Personally, if a reseller just take my money for the sale revenue and throw the support task to other people, why would I pay him ?
Some department must remain in-house rather than out-source
1. Sales
2. Support (main support)
Thank you,
