Shocking After sale service.

Immediately after installation I was asked for a review. Decided to wait to see rather after sales service. And this is when they have already 100% payment. I would definitely not recommend them again as I have done. Soon as you have paid them there is no after sales service. And I can see other people had similar complaints regarding their after sale service. 1) First battle to get my COC certificate 2) The SSEG inspector had some issues, that they have not bother to come fix. 3) Asking about warranty on the system, never received given a clear answer how it will work and the process. 4) After more than a month got the system eventually on my phone, now it disappear and battling to get it back. 5) Asked also various times to give me a demonstration of the setup, just ignored. 6) They were working next door at the neighbor ask them twice to come and assist, and now I see they just disappeared. Sending multiple emails and most of the times they do not even bother to answer.
