Installation did not happen as scheduled

Dear Admin,<br> <br> I write this complain with anger and I know you do not care how angry iam.<br> <br> I have issues with your technicians and callcentre agents last week friday(21/08/2015),saying that my installation is scheduled for Thursday(27/08/2015) between 07:00 and 16:00.So I am away from home and my wife took a day off to give access to our home for installation but an agent called me on Monday to reschedule the installation for tuesday and I declined then on Wednesday the technician called me saying his at my gate but I told him I am away and my wife is at work. <br> <br> I told him to stick to the sms appoint and he said his going to send the order back to you.<br> <br> Today my wife stayed home and waited for the technician to come but thetr did noy pitch or call to explain.<br> <br> I had to deal with your agents who kept me on da line for too long and hang up..<br> <br> what do I do moving forward?are you still going to do my installation?
