Understand that the solicitor that you have been talking to regards you as a feckless wimp. Sort of like a little gnat that might be an annoyance she can ignore or swat and kill. She and her colleagues are probably chuckling that you think they’re going to help you.
So do you want your stuff or don’t you? If you want your stuff, you gotta pay.
Since she is going to have your stuff destroyed in a few days, time is of the essence. Get to your own solicitor now and get him or her engaged NOW. It may not even require getting a court involved. Your solicitor can call the other solicitor and inform her that you are serious and are prepared to make life hard for her. They may be able to negotiate a delay of a few days during which you can get your stuff out. If not, your solicitor knows what papers to file in court.
If this were the United States, it is unlikely that you could get a full-blown hearing with Perry Mason-style questioning and witnesses breaking down on the stand in the next few days. The best you could hope for would be a temporary restraining order until a hearing can be scheduled.
