I have no landline at the moment and booked an appointment over the phone for an engineer to come out this weekend. However, I've just logged into my account and saw that although the appointment for Saturday is showing up correctly, it also said I had an 8am-4pm slot booked for an engineer to come out today, which I certainly did not book. I've cancelled it online but am now concerned why this happened, whether there are going to be any repercussions if an engineer has tried to visit today and found noone at the property, and - most importantly - whether the Saturday appointment has actually been booked properly. Can someone please check?
