Property Management company resigned?

Hello, I am a landlord of a flat within an estate and have been paying service charges to a property management company (Company B). The maintenance for the estate appears to be controlled by a limited company (company A) which had three directors and the property manager co-acted for company A in doing the maintenance and collecting service charges. The directors of Company A recently all resigned, as did Company B.

All the service charges had gone to a client bank account within company B. Company B appears to still exist, at least at Co’s house. However, they have taken down their website, are now acting under a different name and refuse to talk to the leaseholders.

Has anyone else had this problem? We the leaseholders now have no maintenance company doing our maintenance nor any directors of the maintenance company. What do we do??

Can Company B simply walk off with our past service charge money?? Company B is part of a larger group.

Can anyone advise on similar situations, please? I appreciate we need legal advice, but since we as a leaseholder group have no funds, since they all went to the property management company, it’s a tad tricky!

Thanks,

Andy
