Harassment

I would give these people 0 stars if possible. I paid my rent everymonth and they received it, no problems. I moved out of my flat 31st October, paid everything owing on 24th December as I had arranged. Thought everything was fine. 2 months on, non stop harassment! I owe money, case has been made etc. I send them bank statements, eft receipts numerous times. Still harassing me for money I paid 2 months back. They do not reply to my details or anything. Completely *********** and unresponsive.
