Notice of un paid electricity and un paid water bill by house owner

What was the written contract between you the flat owner? Unless the same is read and discovered if any finer languages were written therein, nothing can be said. The contract is an important document. Whether you stayed @ 11 months leave and license or for a specific contracted period ? What is written in the legal notice sent by his advocate ? Unless these are known, no guidance can be given to you. Contract document is very important. 

Don't fall in the trap of any advocate who may suggest you to be in touch with him/her.
