The first question is why are you being charged levies to themOC. I understand that under a commercial lease the tenant pays outgoings but I would argue that the lease paused whilst the renovations were going on.
The lease exists between you and the landlord.
You have probably decided to “ maintain “ the lease so you can trade in the same location when the renovations have resumed. That may have been a good thought at the time, but seems to have backfired for you.
Your situation is not a strata matter, but related to commercial leases. I’d advise consulting a lawyer for the reason that it’s a complicated situation you are in.
