Still No Install!!!

We app**** for a new line to be installed on the 29/07/2015, we were informed within 7 - 14 working days our line will be installed. It's now the 14/08/2015 and still no line!!!! A technician was dispatched to our premises yesterday as per sms received. NO one came once again!. However they logged on the system the tech tried calling my Husband yesterday, there was no miss call!!!!!. I've tried contacting Liberty Mall as usual no answer on the phones. Have been speaking to consultants on 10210 from my Cell, and not much help either. I've paid my deposit which they were quick to receive on the 29/07/2015 but taking their own sweet time on getting my line installed, very very poor service. I'm not impressed at all. I've been informed yesterday afternoon a technician will be despatched today, as per the consultants on 10210 nothing is showing that a tech will be despatched today! This is absolutely shocking and to find the techs are lying and saying they have tried contacting us but no miss calls on our phones. Easy way to get off as it was close to knock off time.
