Tenant left the property without served a notice.

Hi there,

I rented out my property for 1 year with 6 months break Clause. I have just returned to the country and found out that I have not received rent for the past 7 months in my account. I also found out property has been
abandoned for that duration. Tenant claimed they have sent me a notice by an email which I haven't received. They had not returned the keys either.

My Question is can I take them to the court for unpaid rent and for the end of tenancy clean, abandoned
property disposal etc.
