Worst service ever !!!

Worst service ever !!! After paying 2 of my accounts in full and wanted to close them , the pathetic service started.

From the beginning I was advise to phone costumer service / admin department to close the accounts and hopefully receive my letter of closure. Then both these departments advise that I would receive my letter mailed after 48 Hours..its been a week and numerous calls later. Every time I phoned the staff became more rude and they all played the blaming game without sorting out anything. In the week that's gone past no letter was send because one of their rude staff members confirmed only today that the letter was not send ????? Will this ever get sorted ???????????????
