Nobroker — Pre paid service not completed

Hi,
We had a pre-paid bathroom cleaning service due on 15th September.
When we did not hear anything from them we contacted their chat.
In the chat we were informed that a different team looks after then and they will call us.
We did not get any call even after following on the chat for three times.
Next day again i followed up on the chat and got the same response that some one will call.
We get a call in the afternoon and he says the cleaning guy can come immediately we told him it is not possible now can you please send him tomorrow. He said he will confirm and call me back in 5 mins.
It has been hours and no update.
