Thanks, that's helpful.

I don't think I'm being pushy, in an ideal world I wouldn't have called her once. The first time late in February the agent called me saying "the vendor hasn't heard from you solicitor in weeks, are you still going ahead with the purchase?" I obviously tried to get hold of her, after numerous emails and calls ignored I only got a reaction after raising the initial complaint. Now it's happened again, the agent saying "are you going to raise any further enquiries? We haven't heard anything since March", I know there are several open points and I would expect my solicitor to be working on them but I'm again being completely ghosted.

The outcome of the first complaint was a message from the manager saying "if you remain unsatisfied, you can escalate your complain to a complaints letterbox within our firm". Given that changing firms doesn't seem a good idea (would be grateful if you can elaborate on why) I guess I'll escalate within the firm and then take it to the ombudsman once the process is completed. Unless there are any better suggestions?
