Selfish and useless service AGAIN!!

Telkom made an appointment with me last week for line reinstall at my new home. They even send me sms to confirm the morning of the installation. No one pitched. When I tried to phone telkom Potch, no one picks up for 100 calls i made. I took off earlt from work, when I got there, the ladies at the front desk cant get hold of the technician, she doesnt know what to do. When I asked her about the fact they dont pick up the phones, they said they are not allowed to pick up phone when busy. I was standing there for 20mins. In that time the phone rang 10times, and they ignored it the whole time. But in that time, as soon as the phone stops ringing, they make there personal calls from the phone in the shop(not allowed to use phone).. They said they will phone me on Monday, its Tuesday already, I still havent received any feedback, I still have no telephone line, and ironically i received a bill yesterdag from Telkom, which I will not pay!!! I just want to say if you are too lazy to do your job, get rid of those people. They are giving places like Telkom a bad name!!! I am very dissappointes and very frustrated withthem. They are rude, selfish and useless!!!
