Shocking fibre service from NEOTEL

I opened a new restaurant on 15 Dec and was guaranteed by Neotel that my fibre would be installed and up and running in time for our opening. It is now 7 weeks later and i am still not connected. I have sent 11 emails and called 23 times with no response. I have threatened to go to social media and still can't get a response. It is difficult to believe that in times like these, companies still think they can get away with providing shocking service. Fibre is a competitive industry Neotel - wake up and look after your customers - before you end up with none!
