Extremely bad service provider who has no clue of CUSTOMER SERVICE!

My wifi has been off since 16 April 2021. I send 2 emails on 23 and 30 April to *** with no response. The person Ethan Jacobs who installed this for me can not give me any answers as he has no clue when the service will be up and running. The service from this company is the worst I have ever experienced. Whenever I call the automated voice message just says they are working on it and keeps saying my call is first in line but no one answers. As we pay for this service in advance I need a total refund for the 15 days my wifi has been off from 16 to 30 April and for this to be cancelled. I hope someone will get back to me on this platform!
