*******ly evicted from my flat!

I entered into a 12month lease agreement with City property from March this year and this month I had trouble with paying my rent on time. I arrived today to find locks had been changed! I understand that Iam late which is why I even tried to make arrangements with their credit control but nobody picked up the phone hence I even left voicemails! Where am I supposed to sleep tonight? Is this not an ******* eviction by city property!?
