On-site technical support ! 

On-site technical support has its advantages.
No need to unplug everything, take it to a store and try to explain the issue. Leave it there and hope it gets fixed. Then bring it back and put it all back together.

On-site technical support allows you to be part of the process. You get to observe and provide input  that will ensure the service is completed to your full satisfaction.

In addition, there is no over-selling of services.
You get exactly what you need
