Recovery of maintenance charges by new flat purchasers from old society members in redeveloped soc.

I recently purchased a flat in a 28 storey redeveloped building. The land owner of the property is MHADA. There are 40 members from old society whose old building(4 storey) was redeveloped into this new 28 storey building. The OC for redeveloped building was received in Feb 2022 and I received the possession of the flat in Apr 2022. I had paid 1 year maintenance charges to the developer as part of agreement from the date of receiving OC. The developer had been maintaining the building since Feb 2022. The developer(Promoter) offered the possession of the flats to 40 members from old society after receiving the OC. As there was an ongoing dispute between the developer and 40 members from old society, they initially did not took the possession of the flats immediately in Feb 2022. Couple of months later, few members(approx.20) took the possession of the flats from developer. However, their new flats are still not registered due to ongoing financial dispute with developer. The developer has still offered to register their new flats and is ready to settle the dispute by paying 'x' amount to them. However, these old members are adamant on their demand of receiving 'y' amount. During this course, the maintenance period of 1 year from date of OC expired. A delegation of new flat purchasers approached the developer to take additional maintenance charge till handover of the project to old society managing committee. Developer agreed for the same and we paid charges for additional charges for 3 months to developer. The developer during this period of 3 months handed over the project to managing committee of old society(Co-promoter). However, the managing committee is denying that they have officially taken the handover from developer. Nor the developer if providing evidence backing his claim of handover to society. A delegation of new flat purchasers also approached the managing committee of old society requesting them to pay their share of maintenance charges. However, the old society members are not ready to contribute any amount towards the maintenance charges for reason known good to them. The new flat purchasers are voluntarily raising amount towards the maintenance charges and are paying for the necessary services like common electricity bills, housekeeping, security services. Additionally, though the developer has sent the society memberships forms of all new flat purchasers to the managing committee. The managing committee of old society have still not accepted the membership request. It's been almost 3 months since the submission of membership forms, but the managing committee are not ready to accept the applications form, nor they are providing any written explanation for the delay or refusal. Now that the new flat purchasers are maintaining the building, is there any legal provision to recover the maintenance amount from old society members? If yes, what are the legal steps and duration this recovery can be done?
