Extremely poor service

I ordered my fibre installation in August last year. To date they have not installed the fibre. They constantly have excuses. Towards the ending of last year I was told my installation will be done in Jan or early Feb. When I emailed them to query where they are with the process, they now tell me possibly March. I have been dealing with Ushma Dahya and her team, who only provide you with feedback if you follow-up with them. They don't take any initiative to keep you updated with progress. Their response time to your email takes several days. Even then you have to send follow-up emails requesting feedback on your original email. When you phone the call centre, they hang up on you. I've never before experienced such terrible service
