These guys are so unreliable and blatantly lie to customers!! They have me an appointment for between 8-9am as the engineers first job so I made arrangements for someone to have the morning off work and be there to let the engineer in. He didn't turn up!!! They then tell me that they never gave me an appointment for that time and that my appointment was before 12pm. The rude lady answering customer services calls (and strangely claiming to be a manager) refused to listen to the recorded phone call that would confirm I was right. I guess that's because the lady I was speaking to was the same person that made the appointment and didn't want to be confirmed as a liar. They also charge your card in advance before even doing anything. Another sign of a bad company. Save yourself the hassle and stay away from these cowboys!!!
