Incompetency And Laziness At Work For Almost 2 Months!

I really never seen such a very bad service even when you escalate the issue to their Specialist Case Managers instead it's even worse, it's almost 2 months they failed totally to give me the correct information I request from them instead they send me the incorrect bank statement from another person whom we share the very same surname, every time when I need feedback I have to call Daphne le Grange and She sometimes not even know what I have been requested and started to read my email while I am waiting over the phone.....MY REQUEST TO THEM WAS VERY SIMPLE is to tell me how much money I have been paid so far on the Bond Account and how much interest accumulated, I know I am stupid but when I spoke to them I feel a lot better!!! that's how I feel in terms of competency...
