Disconnected 3 x in a week

This is the 3rd time since 8 Sept 2015 that the service on one of my smartcards, ending with ....091, has been disconnected for no reason. Payment is done by debit order yet the screen message mentions \Account in arrears"What makes it worse is that I am not able to speak to a consultant when calling your client service centers (011 - *** or *** ) and there is no option I can choose from to help me. I have been to the client service center twice and no one can tell me why it is happening - all that they do is reconnect it every time. I must take hours off from work to sort out these issues. The self help service is not working for me now as the card is not linked after I've requested it twice. Absolutely ridiculous!"""
