UNABLE TO CONTACT BUSINESS- POSSIBLE ****

A tehcnician named Silu came to my house to replace my MacBook's keyboard as certain buttons weren't working. However, now I am unable to connect to wifi so he must have shifted some connection. I have been trying to get a hold of him using both numbers advertised on their website, as well as their email address, to absolutely no avail. Starting to think this might have been a ****?
