Sale of Grade 2 listed cottage

Lots of early promise but not followed up with driving the sale forward. Appalling communication, sometimes upto 3 weeks between updates. AG claim to be specialists in these types of buildings but saw no evidence of this. A huge bill for very very little effort. I would never use them again. They offered no added valve over and above an online agent such as purple bricks. The office is extremely small and inpersonal meaning it's impossible to hold a private conversation and one member of staff couldn't even find our details on their system 3 days before exchange of contracts. No log in details provided for their on line property sale/ tracking portal so cannot comment on this. Hopeless. With this level of service it's no wonder online portals are taking over, saving you a huge amount of money.
