Failed to meet appointment

I had an appointment on Wednesday, which I waited for close to a month, to have an ADSL line installed in my flat. None of your people showed up, I didn't get a phone call or anything. When I phoned to investigate why they haven't showed up, the support agent said that the reason was workload and that they will send me an sms to schedule another appointment. I haven't received any sms as yet. I have no idea what is going on and if anybody from your side is going to come and install the line.<br> <br> Please can you get somebody to contact me about when you will come to install the line.
