Payment demands and closing unsolved HP queries

As the incorrect debit dates caused for bank charges due to returned debit orders and unpaid amounts added to my account, I was promised that these cost will be credited to my account and this will either cover my account for April 2015 or I will have to pay in the difference. They then requested my bank statements in order to determine the credit amount and after calculating the amount they promised to contact me to inform me if I need to pay the difference or if amount is covered. I then sent my bank statements to them in April and I am still waiting on feedback even though the case is closed on their side. <br> Up until today I have not received any feedback from them but yet they keep suspending my line due to none payment even though I don't know how much i must pay. They call threatening me to pay but cannot give me an amount. I call them every second day requesting the amount and everytime get told that they have escalated the matter, will sent emails to the agent who handled the matter,someone will call me but no one ever does.<br> Im sure this is in breach of CPA and cannot see how anyone can do business with such people. I need a number of the ombudsman or someone.
