<human>: Provide a brief overview of the text.

I got a email today from my estate agent.

They want money from us and are not returning our deposit - because we didn't pay the last two month's rent.

Why didn't we do such a obvious thing? Because since the start of our tenancy we didn't have any running hot water. We contacted the landlord about this at the start of our tenancy, and informed the agency repeatedly that we were withholding rent for this exact reason. They had no complaint about it, but it was never fixed. 

Our contract says that if either side does not keep their side of the contract fulfilled, the other side can act appropriately.

We will look over the contract again and contact a lawyer of some description about it. 

In the meantime, can we do anything about this issue? We are in the UK.
<bot>: No hot running water for year, didn't pay last 2 months of rent, estate agent or landlord did nothing about it, now want us to pay rent. What do?
