Angry users of Southall Community Centre have vowed to fight on after being given notice to quit the site by the new owners.
Peter Sylvester, vice-chairman of Southall Community Association (SCA) said he received a letter last week giving the group six months to get out.
In July the association said it felt "slapped in the face" after Ealing Council sold the site to new charity Go Help Asia Trust for £2.2million.
Mr Sylvester said: "We do feel betrayed, not just by the new owners but by Ealing Council. The centre should never have been put up for sale to a private owner in the first place.
"We have been told our tenancy is being brought to an end as the trust wishes to close part of the site for refurbishment or to demolish it.
"We are speaking to lawyers over the matter and it is our intention to fight this as we believe there is no legitimate case for bringing our tenancy to an end.
"This building was given to the people of Southall by local businessmen in 1920, and it should be kept for that purpose.
"The presence of the SCA is the only thing that guarantees local community, sporting and religious user groups will be able to use the site."
Earlier this year, Gurmail Malhi, one of four trustees with Go Help Asia Trust, told the Gazette he wanted to work with SCA in upgrading the building.
But on Wednesday he said he had given the group notice to quit as they were not co-operating with him.
He said he still planned to get repair work done at the centre so it can be used by the whole community.
Mr Sylvester said SCA had had difficulty in getting Mr Malhi to attend regular meetings to discuss management of the site.
Ealing Council declined to comment on the issue.
