If you don't have a service contract, you can purchase per-incident support from the VMware Online Store. That's essential a "credit" or "voucher" for you to open a service request. Opening a service request online should then ask you for the "serial number" or something of that ilk that represents the per-incident support that you purchased in the store.
If you were within 30 days of purchasing a new or upgrade license, they have complimentary support to open a support request. The bad thing about that is that most folks don't find things that need attention until after that 30 days are up.
