We were due to exchange on the 9th November with our buyers wanting to Complete on the 22nd November, on the 8th November we noticed that the website and app wasn't responding. We filled in the online form, our conveyancer, Holly, told us she couldn't get into the system, we would have to wait. I submitted another contact form the following week, explained that our buyers were elderly people who had moved out of their home and were in effect homeless. We eventually exchanged and completed on the 30th November, 8 days later. I believe our sale was prioritised owing to our buyers circumstances. Other than the IT outage that delayed our sale we personally found our conveyancer to be spot on for communication, response times and efficiency. Sad to hear about the woes of others, we can empathise with your plight, earlier in the year someone in our chain pulled out on exchange day, apparently in a 'fit of pique'. Our buyers had to resell their property. The old saying "patience is a virtue" has tested us to the limit.
