Disrespectfull, Contradicting Contractual Policies and Intimodation

What a horrible experience, intimidated, threatened and belittled. They contradic their own policies, change contractual rules as they please etc. I lost my job amd my affordability went down, I then ended my lease and paying the penalty, arranging to pay the shortfall on my account. Rudely putting the phone in my ear while I talk, threatening to blacklist me; in that event I will approach the ombudsman. When you sign and pay you are the perfect client, at the end of the relationship you are treated very disrespectfully. They, now, they want to phone irrelevant people who no longer reside and or part of the lease agreement, futher demoralising me my and damaging my reputation. I have requested a payment arrangement, no response amd arrogantly been intimidated via phonecall.
