I don't use Facebook, but I did subscribe a year or so ago. I have recently bought a new house which is due to be rented out - and have lost the alarm code, I haven't used it whilst the house was having work done on it. I asked the agents who dealt with the sale to contact the previous owners a few days ago. They say they have left messages but not heard back from the previous owners. They were nice people - I didn't have much to do with them but they seemed nice and we had no issues over the sale. I have just found her name on Facebook and am pretty certain it is her. I don't feel comfortable really, contacting her to ask for the alarm code, but I don't really understand how people use Facebook anyway. So - WIBU to contact her in this way? The only other option is to phone her husband at work, I believe he works for a large organisation, but I very much doubt if they would put me straight through to him and I would be in the same situation, of leaving it to someone else to pass on a message, not really knowing if it had got through to them.
