Definitely write the statement it will take a few minutes and these vendors deserve to be sued for breach of contract by the estate agents.
When you do find another house, please post and tell us. Nothing warms the cockles more than a happy ending.
My last house buying was 10 years ago. Viewed 2 properties which were identical (same builder on an estate) viewed one of them a second time as it was in a better position, but lost out to another buyer.
Asked for a second viewing on the second property but was told the property was temporarily paused and I could only view it if I made an offer beforehand. WTF? I explained it was a second viewing and asked if it was paused because they had submitted a planning application to extend it? The EA said what planning application? So I emailed them the link whilst I was on the phone. They were in shock, had no idea. I told them I was not willing to put in an offer before viewing it again. We were at an impasse.
Luckily another house came on that day, we viewed it, loved it and have lived here for 10 years.
