Unprofessional

I have an account that was in arrears as I had lost my job. Upon finding a new job, I called and made an arrangement to pay the account, once the arrangement was made through the customer service collections department I then requested a letter that states that we have this arrangement in place. I was flatly told by the agent that they do not give out such letters. I then requested to speak to a supervisor who the told me no because customers have used these letters in the past to bring the TFG brand into disrepute!!! Even after I explained why I needed the letter. <br> <br> I called the following day and dealt with a different agent and supervisor and they said they would have it emailed to me. 2 days later still no letter! <br> So now I have paid the account and it is no longer in arrears. I request a letter that says as much or a detailed invoice statement that shows the payments I have made over the last 4 weeks and no one is willing to assist me. <br> <br> I have dealt with rude, unprofessional agents who all say different things, no one seems to know the company procedures and I was kept on hold for ages. Transferred from one department to another with no solution!!!
