yes they can - if you are in financial trouble and need to stop your situation getting worse, go to the cab and get them to help you. they can approach lenders, get them to stop charging interest and negotiate affordable repayments while things are tough. there are long term consequences of doing this (sometimes bailliffs can get involved, ccj's or even bankruptcy) but surely it has to be better than struggling, stressing and making the original problem a whole lot worse? do something now!
