South Swindon MP Robert Buckland has secured a meeting with Persimmon Homes for residents who say they were mis-sold leaseholds.
Mr Buckland has pledged to do all he can to help people affected.
He said: "Over the past year or so, I have been acting on behalf of many local residents in the Badbury Park area who believe that they have been mis-sold leasehold properties by Persimmon Homes.
"I have been pressing Persimmon for a residents' meeting for many months, and following the appointment of Julian Roper as Director in Charge for Persimmon in July, Persimmon finally agreed to this request.
"Due to covid-19 and GDPR it was agreed that these meetings will take place on an individual basis rather than a group meeting, at the Persimmon show home in Badbury Park on Friday 18 Sept.
"I will also be present at these meetings to represent and support local residents.
"Due to high demand for meetings, all slots are now fully booked, however, Julian Roper from Persimmon has agreed to review any individual cases where a resident has been unable to book a slot.
"I have also requested a public Zoom meeting with Persimmon which Julian Roper has turned down. This is disappointing news."
Mr Buckland added that he was pleased last year when the Ministry of Housing, Community and Local Government announced that all new build homes will be sold as freehold in a move to tackle unfair leasehold practices.
He said: "This is a step in the right direction; however, it does not solve the issues for the many residents, including those in Badbury Park, who have already purchased a Leasehold home.
"I have written to the Secretary of State for Housing, Communities and Local Government, The Rt Hon Robert Jenrick MP, on behalf of local residents and asked him what can be done from a Government point of view to help those residents who have already purchased a leasehold property.
"I will continue to work hard and do all I can to assist residents with this issue."
