Supertech — facing problem sealant in walls for six months

Hi,
I live in supertch eco village ii in greater noida. I am facing problem sealant in walls for six months. I have registered complaint so many times. But there is no action taken by maintenance office. Maintenance forward the complaint to tower incharge and he always says that this issue can only be resolved by maintenance office. I don't know where to go and who is the responsible person to resolve this issue. Kindly resolve this issue at your end as soon as possible. My tower is b1.
