Poor after sales service.

I had the installation done about a year ago. Had to call the CEO to get things rolling eventually. After that they jumped through hoops to get things done. All went well until recently when my house insurance wanted a form filled out for my insurance. Do you think I can get hold of them? I have sent several emails in which I have sent the form to be filled in. I don't think they read emails. I eventually got a private electrician to see if he could check the installation and fill in the form. After checking he said that he cannot fill in the form as the installation is not compliant with COC rules. Today I attempted to call, but that was answered by an electronic service, then hung up after waiting for some time.

I need to get this sorted out as I need a valid COC.

Wetility needs an effective answering service to deal with faults and enquiries.

The public should know that there does not seem to be any after sales services.
